• Color stimulation in LPS

  • Monique1236

But I still don't understand how this happens and what exactly affects color saturation. Since there are no explanations from the owners of LPS either. What factor triggers the mechanism of protein synthesis responsible for coloration?

Cynthia6578

The main thing is the spectrum. All fluorescent proteins in corals are essentially a protective mechanism against overexposure to light of various wavelengths. Regarding the different architecture of skeletons, the current plays a key role here.

Michele

Hmm... It's tough, I agree. But what a result! By the way, for the last two days, I've been trying to find this thing that Americans use. So, all the suppliers are wide-eyed - what pellets for LPS??? Only liquid amino... Just like that... And for the enemies, it's already outdated, an obvious fact. It doesn't mess with the water, and the corals are grateful. In Russia, they didn't really give me an answer about this feed either. Although Tkachev sells this manufacturer's chemicals. The girl even tried to make a sarcastic remark over the phone, asking where I read about it, like I'm some kind of fantasist.

Michelle5859

I looked at it, it's an interesting product. And the price (on that site) is quite reasonable. Since it's made in Germany, maybe iREEF can help? Did they not ask them?

Anne

It is being produced, but they are working with other brands. However, Denis said yesterday that he would try. There are plans for a dealership with this company. But for now, everything is uncertain. We'll just have to wait... Is there really nothing interesting happening with colors for anyone? If that's the case, everything will come down to feed.

Jeremy8404

Corals would rather be considered plants.

Michelle5859

You hit the nail on the head!

Joyce

Thank you for the "educational moment," sure... Just Google it. Melanin in the body is found in a complex with a protein molecule, and often in popular publications, they write protein-melanin, but it is NOT a protein itself!

Adam

You forgot about another option - the mindless expulsion of mucus with excess zooxanthellae. This is often done by anemones and LPS. As for the endless reproduction of zooxanthellae, their number is limited simply by the available surface area of the coral, where they will have enough light. That's all. I didn't understand this paragraph at all... How and to whom can a coral not reduce the supply of metabolic exchange? What substances? To whom is the supply?

Alicia5489

Let me provide an introduction. The book by N. Deikin, pages 148, 149, 154, 156, 160, 180. There are lines such as "...each type of symbiotic algae (zooxanthellae) gives the mollusk (read coral) a unique pattern and color, which can be shades of blue, brown, gray, white, orange, yellow, purple, and red. Some colors have the ability to glow..." Regarding bleaching, there is information in the book by O. Savchuk "Reef Aquarium," page 249.

John3432

Yes, because it is written in Russian that this is a non-proteinogenic amino acid! And it is from this that melanin is synthesized! And if you show me the word "protein" in relation to melanin in your own link, then I will take back my words (which you nitpicked and expressed deep distrust in)!

Christopher4108

I can't understand what you want to say. That corals are not colored solely by zooxanthellae? Well, no one denies that. How to stimulate the synthesis of fluorescent proteins? That's also clear - provide the spectrum and intensity of radiation under which the coral will be forced to protect itself, and give the "iki" (amino acids, vitamins) from which the coral will synthesize proteins. The link to the feed is VERY interesting; if I can order it, I wouldn't mind having some as well. Especially since the package is almost half a kilogram, it can be ordered for two or three people for a trial.

Teresa

That's exactly what I was saying! And you were like "how can we believe after that" and so on. Alright, let's move on. Regarding the spectrum - to stimulate the maximum spectrum of proteins, a wide spectrum of lamps is usually used. In terms of color temperature, this ranges from 10,000 to 20,000K (nothing higher has been invented yet). The wavelengths of lamps from each manufacturer differ slightly, so you need to look at the spectrogram. Also, the intensity should be decent, meaning the power of the lamps and a small depth.

Jennifer5371

And if it works out with the feed, it would be very interesting to see the results! By the way, it would be nice to create a thread about your aquarium with photos to compare "before" and "after."

Lindsey3628

Regarding zooxanthellae. When adapting to unfavorable conditions, corals begin to increase the number of zooxanthellae by growing the mesoglea. Okay, understood. However... the coral does not become brighter as a result. This means that zooxanthellae do not have such a strong influence on the overall coloration? But here’s an interesting point. The coral itself does not seem to synthesize tyrosine? Yet, somehow the polyps produce beta-carotene... and possibly zooxanthellae as well. It turns out that it only gets to the coral through food. If it is given this amino acid, it will be easier for it to synthesize carotene, which is responsible for yellow, orange, and red colors.

Erin

I don't know. Where is the information from? Tyrosine seems to be a non-essential amino acid.

Amy5070

Not just reflection, but UV reflection with a shift in wavelength to the visible range. Pigments, by absorbing energy, direct it towards the synthesis of organic matter, while proteins, taking in light energy, reflect it in any case, shifting the wavelength. The reflected light can either be in the range visible to us (fluorescence and simply "color") or in the infrared (just heating, which you apparently referred to as "absorption").

Jacob4800

So far, this is all I found. As for easier options. More interesting ones involve coming up with the feed myself... Nevertheless, thank you for getting involved, there is already a first review of the feed. I like that the feed doesn't spoil the water if it's served in pellets like this.

Danny

I was talking about the absorption of light by pigments. And reflection by proteins. And the shift of the spectrum into the infrared zone - that's interesting... So, let's try to summarize. If I'm wrong, please correct me. If we want to enhance fluorescence, we stimulate it with UV light. The coral produces more and more proteins, and fluorescence progresses. But if we don't want fluorescence and just want a bright contrasting color, do we need to achieve pigment synthesis? Or better yet, both together.

Lauren

In vertebrates, it is definitely replaceable. Below, in chordates, it is closer to yes than no. In corals, there are significant doubts. There is nothing. So far, nothing has been found.

Anne

It's the same; in long-wave UV, proteins will fluoresce, while in regular light, they will have a bright contrasting color.

Breanna9982

I found an interesting scientific paper. Here is a quote: - And here is its sensational result: for most fluorescent and even ordinary dyes (which include all the colors of the rainbow!), the non-luminescent species of corals and possibly other cnidarians are not actually responsible for heterogeneous low-molecular-weight "pigments" and their complexes with proteins, as previously thought, but rather a peculiar family of proteins related to GFP. Here is the paper macroevolution.narod.ru/labas4.doc Phew... Finally, we have figured out what is responsible for the color of corals.

Laura4892

It depends on which MG, and you also need to combine MG with T-5. Then the unpleasant brownness goes away.

Wendy2244

This is with combinations of Mg and T5. One person even had 5 incoming species of acan that started losing their colors, leaving only red. He has a 160-liter aquarium and only 5 T5 lights. Shading restores the colors.

Lauren

And is the first Acanthastrea also in the shade now or..?

Scott9892

No, the first one is currently at the bottom in the light. Just like in its first photo. By the way, the sick one just released its feeding tentacles when I was feeding the others. It also ate.

Cheryl

As of today, the corals are unchanged. I feed them granulated food from Fauna Marin twice a week. I am also ordering more food from this company for fish and corals as a trial. If anyone is interested in granules for LPS (large-polyp stony corals), feel free to message me. I will include a couple of jars in the order.

Kyle

An interesting experiment. What about the fava bean?

Alicia5489

What can be said now about the ongoing experiment?

Earl

Who can tell me why LPS can lose color? My red lobophyllia initially faded, and now some areas are white.

Stuart

What lighting is it located in?

Brianna

Well, actually, in the middle of the aquarium, it's not in the shade. Out of 10 lamps, I have long been using only 8.

Lauren

Me too. But for some LPSs, even this is too much; they have to hide from the sand in a small shade. You need to try... either a lot of light or little food... but I don't know how often you feed and with what.

Kevin262

She doesn't want to eat; I offered her shrimp and artemia, but she won't take them.

Tracy4603

The experiment is no longer being conducted. It is essentially finished. Certain conclusions have been drawn. Currently, these corals are in another aquarium due to Helman's excessive aggression. The LPS is being completely consumed. The lighting in that aquarium (200L) consists of 22000K T5 bulbs (2 pieces) and a 20000K MH bulb (1 piece). The Favites has become brighter, while the acanthastrea remains unchanged. In that blue light, none of my cameras capture the colors as they are. I want to make a swap now. I will place Helman in the 200L aquarium, where a lot of aiptasia has proliferated. He has already tidied up the other tank a long time ago. The acanthastrea will be moving to the other tank under LED lights. I might take some photos for the occasion.

Jason9385

Lobophyllia are deep-water corals. They cannot tolerate a wide spectrum from yellow to red. They do not like it when strong currents disturb their very fleshy tissues. It seems that this is part of the reason for their refusal to feed. They love to eat. They consume a lot. So the coral is definitely not healthy. And what about the wild coral? Has it been in the wild for a long time?

Stephen5841

Yes. On the official website of Gizman. These are Gizman lamps. I'm too lazy to look for the link.

Scott9892

No, it's Acanthastreia lordensis. The coloration is exactly the same as in my experiment.

Thomas1044

And I'm talking about that. Above 15000K, it's MG. 15000K is the maximum for T5. There's no need to search for a reference, it's not necessary to strain yourself; just write the lamp's marking.

David953

Acanthastreia lordwensis - "The desired combination of words is not found anywhere" - this is what Yandex and Google show, but where else can you search?

Kristen1161

I'm not lazy. For you Regarding "Acanthastrea lordhowensis" - this is Acanthastrea lordhowensis.

Katherine

Oleg, I understand that you refuted their statement by illuminating your aquarium with maximum spectra to spite your enemies. Can you share a photo of your aquarium lit with lamps that have such a harsh color temperature of 20000-22000K? I have four regular T5*39 actinics and one MH*150W (14000K). Is there any point in replacing two regular actinics with Powerchrome actinic plus T5*39 watts?

Jeremy3637

I have a T5 80-watt 22000 actinic+ lamp. I really liked it.

Michelle

Oleg, thank you for the answers, but my posts are not a cry for help or problems. I provided an example of the color and appearance of some corals and I ask you to show just two photos of your aquarium (only T5 is working and T5 + MH are working) to see the effect - DEEP BLUE OCEAN. The cost of this T5 is 253, so the experiment is not cheap. Thank you.

Caleb6320

I didn't mean to offend, sorry. I just have a lot to write. If you want, contact me, we can chat. My phone number is in the post. It's hard to explain everything in just a couple of words. Photos will come later.

Heather2018

Here is the photo. The first one is just T5, the second is T5 and MG. However, my camera is unable to work in such conditions, so these shots cannot convey anything. It recorded video with slightly better quality:
