Reproduction and fragmentation of corals

Alyssa6727

I suggest sharing my experience on coral propagation and fragging. This topic has really intrigued me, as I've started propagating corals myself, and I've realized that it can offset the costs of the aquarium (well, at least in theory) and also makes the sea more accessible for new marine enthusiasts (I've already introduced 4 of my friends to the sea). For those with experience, I propose discussing at least 5 points for each coral/frag: 1. Name, care requirements. 2. The process of separating from the parent coral/rock. 3. In which solutions you soak them before gluing. 4. What glue you use and how you attach them to plugs/rocks. 5. What kind of care you provide

An interesting link on how to fragment coral from one polyp:

It would be interesting for Maks to hear about acres... If it's not a commercial secret, of course...?

Charles5941

There is a good topic about coral fragmentation. Regarding the glue: I use "cold welding" with a mineral filler.

Christopher1774

Yes, there are many different things there, but they are all scattered throughout the forum, and it's hard to find anything... Moreover, everyone has different experiences - it would be good to gather everything here, and maybe they would link to our forum. What kind of welding is that?

Erica

The glue is like that. There is one with a metal filler and one with a mineral filler.

Brooke

And the title?

Tonya

and how did you find such glue? I use this one, read carefully. It is resistant to water, oils, solvents, and alkalis. Recently, I also started using an interesting moisture-resistant epoxy glue. It has good UV resistance and adheres to wet surfaces. Metal powder is absent in the glue component, which is important for our work in the marine aquarium.

Lesha, it's most likely the same thing under different names. The one I use is made in Kharkiv. The description of mine exactly matches the description of the glue in the first link. P.S. By the way, I've been using it for a long time, since the press.

Out of the more than 30 types of cold welds available on the market, only 4-5 are suitable for us, and the rest are not worth considering. To clarify, it's like gradually replacing evaporated water not with osmosis, but by pouring it from the tap, and over time it will become noticeable, not immediately. And the examples I used in the freshwater context are irrelevant, as freshwater is not located near the sea.

Definitely epoxy resin! It is not counterfeit!!! + Very convenient and instantly fixing coral on the plate (when moistened with water) This is such a super moment gel -

Kimberly2102

100%. Therefore, only from practice, sometimes sad.

Patricia

Not bad, and many marine aquarium enthusiasts use it. I tried it, at first it didn't go well, but then I got the hang of it.

Colin1418

By the way, cyanoacrylate is VERY toxic, like all cyanides. I didn't like it because it instantly forms a film underwater and doesn't stick to anything afterward.

Leah

What about the corals? P.S. So far, I have used tuna glue for corals, which is garbage! 20 euros wasted... Now it's either super glue + epoxy or the same tuna glue...

Phyllis

I didn't understand the question to me? Which tuna one? I'm buying 8 pieces of Henkel epoxy for 20 euros and 5 pieces of gel.

Jonathon8514

Regarding reproduction/division/fragments, As for the gel... ahem... it costs about 4 euros for a very small tube.

Kimberly3727

Off-topic What secrets to share? Competitor? Germany is sneaking up? Wow. And I've said so much, they might get interested...

Stacy6866

Haha, I will definitely be lurking. Soon I will start bringing in Vietnamese umbrellas (by the way, if anyone has some, could you share a couple of varieties with 3-5 little ones?) but ones that are really beautiful? Because in poor Germany, there are no supplies from Vietnam... To be precise, I haven't seen or heard of them anywhere yet...

Charles4157

Epoxy resin has now been translated... and it has also increased in price significantly... so now it makes sense to buy the branded one.

Daniel132

Tanya, it costs 29.90 in supermarkets, while at the market it's 25.50. You can also find an old gray one with white at the markets.

Danielle9144

Well, if it's old, that's good... but I found a good replacement...

Dennis

Will the Momento epoxy resin work? P.S. I’ve probably tried 3-4 different brands of coral glues, and none of them were satisfactory. Gluing underwater is not an option with them; I struggled to make it work...

Johnny

I think you can buy quality there, I used to use it before. But lately, they have started bringing in a new blue one, it's rubbery, doesn't stick, creates dust, smells... and so on...

Lauren

They brought me Moment Epoxilin from Kyiv.

Heather2018

In my opinion, it's best to frag, and the sooner the better. Break it in such a way that a little live coral remains on the base (there should be no signs of disease or anything like that on the broken piece). In one such case, I used gel glue. Everything grew back onto the frag pretty quickly.

Alexandra

Another question: who knows how Trachyphyllia reproduce, and is there a possibility to breed them in an aquarium?

Omar3497

So yes... it's easier to break than to build... I already tried to do it, and by morning a branch had broken off, that's why I asked...

Gabriel

Gentlemen, who knows any ways to stimulate enhanced growth for umbrellas? For example, what light is best for them? Current? What feed and how often?

Chelsea567

At the marine fauna, there is Ricordea / Food, I haven't tried it myself.

Randy

Thank you! I found it... Wow, 250ml costs 44 euros!

Rachael

Look, there's something interesting here too.

Tina

Yes, indeed... I need to take some time to read... A good description of the product... And for me, it's especially useful since there are a lot of TM in Germany... As for umbrellas, I read somewhere that they like the blue spectrum of light? Is that true?

Amber1273

Indeed, they shine beautifully in green then, but according to researchers, this is a protective reaction to such lighting. Nevertheless, I haven't noticed it harming them.

Nicholas2252

I meant for growth, especially for the colored umbrellas...

Zoe7451

On Aqua Logo, there is a guy named Krang. He is very responsive. He has some gorgeous Zoanthids. He shares his knowledge and secrets in his thread. Or are you talking about which "umbrellas"?

Kristen2246

Just one observation regarding the light. At the end of February, I set up a 140-liter aquarium for fish and still haven't ordered a proper marine light for it. For now, there are two 30W energy-saving bulbs shining in reflectors with good reflectors. I also placed some small frags there, including umbrellas. The colors of the corals are, of course, terrible and horribly distorted, the light has a yellow tint, but I was surprised to notice that the same umbrellas, mushrooms, and various clavularia are doing quite well; no one is stretching, and they are growing reasonably. The white Xenia didn't like it, though the blue frag settled in well there.

Tasha

I read his useful topics... but there are many uncertainties... So I'm clarifying... Maybe someone else has some experience...

Colin1418

the most luxurious point that solves everything: 19. Mood, yes, the zookeepers may simply not be in the mood to open on a certain day without any objective reasons. I have a question more about how to enhance or stimulate their growth...

Alan273

It varies. Some of them spread well in current and bright light, while others, on the contrary, do so in shade and weak current. I don't feed them specifically. Green zoanthids under blue light (night lighting with LEDs) really fluoresce green. I haven't seen any harm from this.

Tasha

Not like that. At least for me. In the aquarium with a lot of ultraviolet light, both from T5 and from MH, they grow slower than in the aquarium under LEDs.
