Pet Forum / Aquaria / Marine Reef / March 2007orange/red digitata turned pink
I bought a orangish red digitata frag several months ago and it looked great and grew fast for a long while. Over a month ago it started turning pink and now it's very pink, I'm afraid to say almost white pink. I've been reading about coral bleaching but nothing really matches my situation. These have been pink for over a month, maybe even a couple of months. The store I bought it from has his "parent" frags growing great. Any idea why this happens and what I can do? It's getting plenty of light from my halides and actinics. Thanks for the advice. B Do you have other corals? If so what other corals do you have? Is the lighting brighter in your tank than the store's tank? Going to a brighter tank, can cause them to lighten their colors, and it can also cause them to darken their colors. Also different nutrient levels in the water can also make a change in lightness and darkness of corals. And other factors of water conditions can cause a change.

This is my first coral. I have other items like a torch, star polpys, etc at the bottom of the tank but no corals like the digitata. All water tests seem fine except I do fight to keep my water hardness up. I do the typical ammonia, nitrite, nitrate, pH, kh, calcium and phosphate tests. Can you think of one I might check into to further examine this problem, if it is one? http://www.geocities.com/bryg30/83106-fulltank.jpg -you can barely see the red/orange digitata in the upper right (under one of the blue-green damsels) back when it was its original color. -Bryan > Do you have other corals?

Yea I can see the montipora in the picture. I don't see anything in there that would cause a problem. What's the reason again that you have that bottle in there? How are your other corals doing? Or maybe I should ask, how are you other Anthozoa doing?

Montiporas like a lot of light, but not like acros do. Could be some but not all of the zooanthellae have been thrown off (perhaps just one type, but not another - hence the color change instead of full blown bleaching...) My first thing to try would be move the digitata lower.. err... just looked at the jpg... it ain't that high up to begin with (I don't keep my sps any deeper than 2-4 inches below water line myself) > You still have other corals besides the montipora.

I've grown montiport right up to the surface of the water under 400w mh lights where the bulbs were about 10" above the water. Of course the corals don't grow very far out of the water :-) Wayne Sallee Wayne's Pets Wayne@WaynesPets.com Add Homonym's home account wrote on 3/12/2007 3:04 PM: > How strong are his halides?

I do remember you asking me that "glass in the tank" question months ago but I never got back to you. I had two decorative Kahlua bottles that I was using for decoration. They have long since been removed as I needed the space for live rock and livestock. Fungia coral doing well, zoos look good and are multiplying well, trumpets multiply too fast it seems. -They split before they are finished with the previous split and the stalks aren't growing fast enough to give them room between each other. Red Lobo brain didn't make it. Right from the start it also turned to pink and was bony for months. One day I just gave up on it... or it gave up on me I should say. I just cut a ton of growth off my star polyps and gave some to the LFS. Getting an aiptasia problem. Inject one and two pop up. I'll probably "rent" a Berghia to help here. Everything seems to be fine or 'normal'. I'm getting tired of cleaning the green algae off the glass though. haha. I have trace phosphates and very little, indirect sunlight hitting the tank, definitely not over feeding. The halides are feeding the algae and I can't do much about it. Getting an aiptasia problem.

Sounds like some low levels of toxin in the water like coper. Coper would not show up on a test kit as it would be too low for any hobby test kit to catch. What kind of water are you using? Also try adding some milk of magnesium. Wayne Sallee Wayne's Pets Wayne@WaynesPets.com B wrote on 3/12/2007 5:27 PM: > Wayne that cracks me up.

I'm afraid I started making my own water from.... <sigh> tap without RODI... a long time back. Actually it was after the brain coral started changing but maybe it didn't help. The water quality out here is very good and I watched a fish store's tanks for a while that also made their water w/out the RODI factor. I was afraid that my water may be a factor but then again, I saw the brain turn before making my own water. Alas, maybe it would have gotten better if I kept buying the RODI. So I'll have to do a water change and test this. Thanks for the copper idea and the help. I'll let you know the results.

Do this every other day about 3 times.

I'm not sure what the outcome should be but, between that and going back to RO/DI, hopefully I'll see some color come back. I didn't do a water change, just started topping off with RO/DI again.

[quoted text clipped - 122 lines] >>>>>>>> >>>>>>>> B It may be that I just missed it, but what is the temperature in your tank? That could be a major factor in the bleaching. Are you sure it was a digitata and not a Seriotopora sp. ? Any leather corals close to it? -Rob Temps within range at all times. digitata is the name I was told by the store and this guys knows his stuff. Looking at pics of the Seriotopora, I wouldn't know the difference if he didn't tell me. I is only pink now, it didn't start that way nor or the "parent" corals orange back at the store's tank. No leathers near it. There is a little glass anemone getting close but not able to touch it yet. I'll be working on that one this weekend.

There are however a lot of different types of montipora. Some, I think are the same species of montipora. Corals growing in different environments will grow differently and this can make it look like a different species. but anyway that's getting off topic :-) Wayne Sallee Wayne's Pets Wayne@WaynesPets.com B wrote on 3/14/2007 6:10 PM: > Temps within range at all times. digitata is the name I was told by the > store and this guys knows his stuff. By the way montipora digitata is the most common montipora sold. It's nice fast growing coral. It works great for giving the fish something to swim in and out of.

Please continue to ramble on as much as you like. It's usefull and interesting. |
