Brothers and sisters who love marine aquaristics! I suggest we discuss the topic of breeding marine fish. Unlike freshwater aquariums, where many experienced aquarists and casual enthusiasts successfully breed both simple guppies and quite complex species of fish for commercial profit or simply out of healthy curiosity, the topic of breeding any marine fish is practically unexplored. I propose we share our experiences: tell what you have tried, heard, or seen regarding the breeding or attempts to breed different species of marine fish, what factors contribute to or hinder marine aquarium enthusiasts from trying to breed a particular species of fish, and share links to the scarce literature that sheds light on the efforts of aquarists to raise offspring in their marine aquariums. I believe that knowledge about breeding marine fish will be useful to many marine aquarium enthusiasts, as the continuation of the species is one of the primary instincts of the beloved marine fish.

Elizabeth6302

As far as I know, it is possible to breed clownfish and cardinalfish in captivity, and I read about pseudocromis in a magazine. That's about it. So the topic will end quickly.

Caitlin3279

But what about skates? Comets? Mandarins? Bullheads? Opisthotonos? And the girls are spawning in the aquariums, but it's hard to raise them... otherwise... The topic won't end quickly if everyone shares something.

Jennifer7159

Maxim, I think that if they spawn but cannot be raised, then it's not breeding. Shrimp larvae also regularly appear in aquariums. But they can't be grown. The surgeons don't even try to spawn, in my opinion. And I didn't say that my list is complete, but there are still few items.

Theresa5149

Surgeons must adhere to strict conditions; there is a rigid framework, and without it, there is nowhere to go. Even Americans still struggle to breed them properly. As for the fact that they spawn but cannot be raised, there are answers: those same females spawn in caves, and when the fry swim out, they are dispersed. However, if one sets a goal, it is possible to raise them. I agree that raising shrimp is difficult, almost impossible, due to metamorphosis. In both marine and freshwater environments, breeding can be done in two ways: either in a general system or in a separate tank branching off from the main system. In such conditions, the percentage of fry raised immediately increases.

Amber

There is, by the way, information about the successful breeding of certain groupers. For example, the comet grouper Calloplesiops altivelis. In the USA. Pseudochromis fridmani is also successfully bred. Here, amphiprions are successfully bred in Kharkiv.

Lori4746

Comets are bred in Russia, just like mandarins... melanopus and pterapogon are also bred. From my experience, I can add that there were spawns of mandarins-dragon Synchiropus stellatus, but I didn't try to raise them because I rationally understood that my system at that time wouldn't handle it, and it was summer, and we all know how it was. At the moment, I would gladly try, but unfortunately, they are no longer available. The quality is not great, but the dances are visible, and there was roe... I checked.

Joseph2576

I want to try to breed ocellaris in the summer if it skips. I know a place where there is an awesome brackish water rotifer near Skadovsk. With that, success is guaranteed.

Collin

Good luck. I am sure you will be able to lift and share this unforgettable experience with us.

Gary6376

I know that ocellaris and melanopus clownfish are successfully bred in Russia. They are also trying to breed pterophyllum.

Brandy

Breeders are great, respect to them. It's not always easy to keep a damn acre here. But they raise fish. I admire them.

Anthony4281

Slavik. Good fellow.

Melissa3820

I agree. The efforts required for breeding are not trivial. But if we're talking about the topic, aside from the comet, everyone is just circling around the clowns and cardinals I've already mentioned. I also mentioned the pseudocromis. Is that it? Once again, I express my opinion that a delayed spark is not yet a success in breeding.

Guy

Here is an interesting link about breeding seahorses, but unfortunately, it is general in nature without any practical advice; the author seems reluctant to share the secrets of breeding...

Michelle

Odessa, you are in the lists of drinkers in Airife))) Are you managing the comments from there?

Russell8484

There is hope that children of healthy parents will not be infected with various diseases that they contract during transfers.

Gabrielle5053

from the commentary booth

Jennifer7159

To be honest, I never thought that you could breed marine fish at home, that's cool.

Jacqueline5976

The topic has stalled, which is a pity. Successful attempts. Clowns tomatoes. Black Sea palemon. Unsuccessful attempts. Sphynx dog. Shrimp camels. There were also spawns of yellowtail chrysipterus, but the larva didn't like the food at that time. I didn't take any photos. Who should I start talking about?

Eric

about everyone.. Both successful and unsuccessful attempts.. )

Caleb6320

You are doing great, you are probably the first one who started serious work on breeding marine shrimp, and we should take our hats off to your experience with amphiprions... I wish you good luck in your research, and please keep us informed about everything, it's incredibly interesting...

Jacqueline6670

That's right, read and check, and best of all, trust your own experience. Everything is different there, including marine aquariums. Here in Kharkiv, guys successfully breed clownfish, tomato clowns, and otocinclus, but no one has seriously dealt with shrimp yet. You say, what to do with bred clownfish, but Russia is so vast, and the AquaLogo forum is at your disposal. Send the bred clownfish to cities, and they will be snatched up in no time. I don't doubt it for a second, just give a shout...

Christopher4108

First, I will provide for the native area with clownfish, and then I will think about where to move next. So let's start with the clownfish step by step. These are today's photos. The hatching is expected in the coming days. The larger the clownfish, the longer the incubation period. For ocellaris, it is 7-9 days, while for tomatoes, it is already 9-11. Personally, the longest I had was 14 days, but that hatching was very stretched out, as the parents released the larvae in small batches over 5 days. This diary has been kept almost from the very beginning of my breeding attempts here. I will continue to post photos with comments as things progress, almost online.

Nicole7122

Very interesting topic and well done work. I wanted to ask about aeration, filtration, and water changes for your shrimp larvae; was there any of this and to what extent? I have been trying to raise amboinensis, but unsuccessfully, and to be honest, I didn't try too hard. I read about breeding debelius, but there was a fairly extensive and complex system organized there, this article:

Stefanie9771

Well, I had a similar experience... I was just scooping out the larvae with a net in the main aquarium, then I transferred them to separate containers with weak aeration using the same water. I fed them with phytoplankton and rotifers, although the rotifers were yeast-based. 5 larvae lasted for 10 days, 1 lasted about 20 days, but eventually, it still got stunted.

John

Bohnenka, NOOO!!! Yeast kolovratka definitely does not work. You can dilute it with yeast, but then you need to feed it with phytoplankton for at least a day. No phytoplankton - no problem. Finely ground and then stirred in water dry spirulina also works.

Gabrielle5053

I will subscribe, it's a very interesting topic.

Stacy6866

Tulle epaulet

Eric8832

In the thread about the sprat and my comments, there is )))) And next to it is my own thread about tomatoes.

Kevin3579

I see, I thought the same, I'll keep this mistake in mind next time. I also started a project with apogons; there was one that looked like a male, and yesterday three large juveniles from Central Asia arrived, which was a good addition. They split into two pairs, and the male is slightly dancing in front of the supposed female. I also put a "pair" of friedmani in a separate 140-liter aquarium, but for now, one is bullying the other, apparently someone else needs to change sex.

Troy8808

Bohnenka, what size are the Friedmans? Because if they are adults and both are males, the death of one of them is inevitable.

Ricky9405

See point 4, but I haven't quite figured out their gender change yet. I read somewhere that they can change sex not necessarily at a young age, from females to males. I also read that supposedly in one group of species of pseudocromis, a male cannot turn back into a female, while in some it can. What is true and to which group the friedmani belong - I don't know, need to dig deeper.

Marie5348

Fidmans and markers definitely do not turn back from male to female. But 4 cm is tolerable. If you can send a photo of both, I will take a look and tell you for sure who it is by sex. I've already got an eye for it.

Jade

Okay, thanks, I'll try to film it tomorrow.

Brandy1134

Hooray!!! I found it!!! I remember seeing a video of the spawning of friedmans somewhere. Here it is.

Mitchell3177

Interesting site. I apologize, I have not a freidmani, but a porphyreus, listed in the price as Pseudochromis Purple, and for some reason I got it in my head that it was about freidmani. I just compared it with their photos and immediately realized it wasn't them. I can't say they are very aggressive towards each other. The individual that is being chased doesn't even try to hide much and behaves quite boldly. Nevertheless, it has been slightly nipped. Here is a photo of the dominant specimen.

Mark7376

Here is a photo of the individual being beaten.

Frederick

Here is a photo of a presumed pair of seals. The male is larger and has a broader snout.

Darrell7542

Bohnenka, the Tylomelania are definitely a pair. The false chrysomelids need to be fed, they are very thin, it's hard to determine the sex. But the dominating one looks very much like a female.

Elizabeth1221

Thank you, that's good if it's a female. And we will feed them, I have had them for 2 days and in this aquarium there is a huge amount of different worms and small crustaceans from copepods to mysids, but these purples seem to be more occupied with disputes.

Elizabeth6302

Today, several escaped larvae have been found on the surface, having gotten away from the care of their father (and partly their mother). Accordingly, there will be a mass hatching tonight. I will collect a bit. Preparations are in full swing; hands should not be put into the aquarium at all – they will bite.

James5032

Have you tried omega-3? Spirulina is more effective in this regard.

Alexander

No, it wasn't necessary.

Mariah

I highly recommend it; it contains a lot of vitamins and polyunsaturated acids that no fish oil can compare to. With sea fish, you won't have any worries at all.

Joseph9057

Thank you, I'm aware, it was just unavailable at that time.

Cynthia

Let's continue the conversation. I didn't overthink it. I picked about ten little ones, sized 2.5-3 mm. By morning, five survived. What can you do—it's the cost of primitive fishing methods (with a cup). A fresh larva looks like this. The male is cleaning the stone again; they will spawn tomorrow or the day after. I'll try to take photos of the process if I catch it, of course.

Shawn

I'm already here. I'm already waiting for the feedback from your producers. The question I have is... Do you give live spirulina? If so, where do you get it? I've read about it - it feels like a super treasure, like the nauplii of Artemia in the world of phytoplankton, and even humans can use it as a main dish.

Kristen2246

By the way, your guesses about the bright light are indirectly confirmed by the words of other breeders. So you are on the right track.

Craig7302

Where can I get it alive? This is what I feed it. As for people, I don't know. The Incas seemed to eat it, but it smells... BRRRR... it smells like a swamp. I also have phytoplankton (I have bottles placed all over the aquarium), but it's unlikely to be spirulina.

Patrick4439

Do you not carbonate anything in the bottles? Just fertilizer?

Jacqueline5976

I tried it last summer, but I didn't notice any difference when adding CO2, so I gave up on it. I do give a little fertilizer (and it's relative—liquid fertilizers for houseplants), literally 2-3-4 drops a week. Honestly, the bottles just sit there for my conscience, "just in case" they might come in handy.))) But I lost the kolovratka.(((

Jeffrey496

It was not possible to take a photo of this spawning. The clowns placed the eggs on a neighboring stone (they alternate them), and it is located very close to the glass, in such a position that you have to twist and turn to snap a shot, and only up close. In general, nothing worked out. The next spawning will be on the correct stone; in the top photo, it is the cleaned area above and to the left of the eggs.

Ryan7682

it's a pity the topic has died down.

Helen

I wonder why in the world, in the sea, no one tries to inject fish with hormones to stimulate spawning (using gonadotropic drugs). The method has been successfully used in freshwater for breeding fish that do not reproduce in captivity. And there are many such fish in the sea.

Travis572

The problem is not in getting the fish to spawn, the problem is in the starter feeds and raising the fry.

Crystal

Come on! There are plenty of such works in scientific periodicals. First of all, by N.G. Emelyanova and D.A. Pavlov. Abudefduf sexfasciatus, Zebrasoma scopus, Dascyllus trimaculatus... All spawn very actively. The question is different - raising the fry. I agree with the previous statement - the main thing is not the spawning, but what and how to do afterwards.

Jacob4800

Hello, I want to buy a couple of camel shrimp.

Robin

Spawning of Monodactylus I keep monodactyls in Black Sea water. The aquarium is a RESAN-500. I change 10 liters of water every week (on weekends I take water from the sea for the change). In winter, it happened that it was cold, and the sea was frozen. Three weeks without a water change, the water level in the aquarium dropped due to evaporation. I started adding fresh water. One of the monodactyls turned black and began to actively chase the other fish. After another addition of fresh water, the monodactyls started to spawn. They immediately greedily ate the eggs. The eggs are small and transparent. Unfortunately, I was not prepared for this.

Christine864

I placed ceramic tiles for the clowns so that it would be convenient to photograph and compiled a complete report on the development of the eggs by days from spawning to hatching. Now, even without counting the days, it is quite easy to determine how many days are left until the larvae hatch. 0 days 1 day 2 days 3 days 4 days 5 days 6 days 7 days 8 days 9 days 10 days And so on.

Nicole2404

All of this is good, of course, BUT... spontaneous spawning in an aquarium is far from rare; however, it has nothing to do with breeding.

Matthew1280

First of all, they are not spontaneous, but stable. Spawning occurs strictly every 10-12 days. Secondly, if this is not breeding, then what do you understand by breeding at all?

George5104

Well... this is definitely breeding, in the previous post there was only caviar.

Jeffrey6189

I have been showing in this same thread since post 19 what I have succeeded and failed at in breeding marine animals. The photo with the eggs is just a stage of development for illustration purposes. Maybe it will help someone.

Robert800

It was a long time ago, I confess, I didn't keep track)))

Frank7213

Do the parents participate in the hatching of the larvae? If not - What if we try as an option to make a container, say 20x20x20 cm, in which 1-2 walls are covered with fine mesh nylon so that the larvae cannot escape and the food does not get out. Such a nursery is located inside the aquarium itself, and water is supplied to it via an airlift for circulation (a primitive filter from a compressor). The day before hatching, a tile with eggs is transferred into it - this can significantly simplify the collection of larvae. Among the advantages, I see that the larvae significantly reduce their energy expenditure on searching for food in a confined space.

Lisa

What if the same container is made of glass and painted black? There are paints that are completely neutral to water, and no weights are needed since the glass will sink anyway. For hygiene reasons, I believe a clean bottom is better.

Justin9867

Molding is certainly not a problem, but not from glass, rather from acrylic... it will be quite heavy to pull out a glass aquarium full of water, and it's also unsafe. The beauty of this bucket is that it has a handle and fits remarkably well in size with the aquarium for the frenatus... it fits perfectly. The top edge fits snugly on three sides of the aquarium, while the fourth side rests on the brace in the middle (the aquarium itself is made of acrylic, so it's unlikely that the glass will break or the brace will crack). I'm thinking about whether I should wrap this bucket in black oracal.

Bryan1851

I have a male ocellaris biting a rock, preparing a place for spawning?

Jamie3553

The most interesting days are beginning. To clarify, the White Spot in the grotto is caviar.

Ashley5975

The minimum task is completed. The chrysipter larva has been obtained, and the most difficult part is done. Now the most challenging part is to rear it!!!!

Andrea8397

This eagle was caught on camera. The enlargement is enormous; in fact, this creature (I measured it specifically) is 1.7 - 1.8 mm from the tip of its nose to the tip of its tail, while one-day-old clownfish are significantly larger. But the fact that they eat the kolovratka is already good.

Joe

What about the chrysipterus? What are their sexual characteristics and how can you tell a male from a female?

Andrew9246

A charming female bamboo shark is looking to meet a noble male for the continuation of the shark lineage. Does anyone have a suitable suitor?

Rebecca1419

Does anyone have the culture of Kolovratka to share? I would be very grateful.

Brent8919

I have saltwater. Come to the office, but call first.
