sen5241b November 24, 2011 November 24, 2011 I got a small brain with a beautiful and unusual orange color. I noticed the flesh is receding around the edges but there is no dead tissue like you see when the coral is infected or when it has Rapid Tissue Necrosis (RTN) or STN. I noticed an emerald crab crawling on it at one point. Where the flesh is receded looks like it was picked clean. My other corals are looking fine although my lobo looks a little bit retracted
Incredible Corals November 24, 2011 November 24, 2011 I would test your water and post the params here. That will help pin point problems.
jason the filter freak November 24, 2011 November 24, 2011 with the age of some of our wamas members I'm betting a receding brain is more of a widespread problem than the board lets on. Whats your flow like across the brain?
Reloadeddevil November 24, 2011 November 24, 2011 Also here is something to consider, crabs and other critters can sense when something is weak, they will take their shot at it, so if you can put that in the refugium for it to recover.
jason the filter freak November 24, 2011 November 24, 2011 ^ not a terrible idea but you'd have to have pretty powerful lighting
Jon Lazar November 24, 2011 November 24, 2011 I got a small brain with a beautiful and unusual orange color.

My other corals are looking fine although my lobo looks a little bit retracted Sounds like it would benefit from some target feeding.
Chad November 24, 2011 November 24, 2011 Where is it placed? If the tissue is expanding across rock, it can cause lacerations on the tissue which could cause it to recede. Also, I agree that target feeding is a good way to help it recover (on sand).
zygote2k November 25, 2011 November 25, 2011 It might recede then start to grow again, but it's usually a goner if that bright green algae sets in on the old skeleton. Watch out for brown jelly which also means death. Many crabs and shrimps are opportunistic feeders and when they find decay, they eat it. Sometimes this causes the coral further damage and then it subsequently dies and the aquarist blames it on his Emerald crab. Most LPS seem to enjoy medium to lower light levels and medium flow. Keep puffy tissued LPS away from sharp objects or rough rock. You can tell where some LPS corals live by examining the bottom of the skeleton. If it's rough, it might have been pried off of the rock or grows encrusting. If it's pointed or conical, it probably came from a sand bed.
sen5241b November 25, 2011 Author November 25, 2011 (edited) Salnity 1.023 Nitrates zero calcium 490 Alk 7 Ph 8.3 temp 79 I had to leave town for 2 days and it has gotten worse and my lobo continues to look bad. It has med flow and light. My hammer, mushrooms (2 kinds), zoas (2 kinds), Echinophyllia (2 kinds), plate (funchia) all look just fine. HELP! I know this pic sucks but you can see the white receding area. Edited November 25, 2011 by sen5241b
sen5241b November 25, 2011 Author November 25, 2011 (edited) Also I think there may have been a small alk swing a week ago. I feed it 5 times a week. Edited November 25, 2011 by sen5241b
sen5241b November 25, 2011 Author November 25, 2011 Yeah it is a tough one. My trumpets, Sinularia and Ricordea are also fine. This is a weird one. seems like I can rule out of the obvious reasons.
Jan November 25, 2011 November 25, 2011 Do you dose magnesium. LPS need magnesium. It looks like it's wasting away. Does it have any polyp extension at all at this point? I'd try placing it in a cup with a little oysterfeast a couple of times a day or turing off powerheads and feed oysterfeast and cyclopeeze. All of my LPS respond very well to oysterfeast and cyclopeeze. They open up nicley when I feed. They also respond well to magnesium. I keep my mag at about 1600. This level helps to keep bryopsis out as well.

overklok November 26, 2011 November 26, 2011 Your alkalinity is too low, get it over 7.5, I would get it into the 8-9 range.
zygote2k November 26, 2011 November 26, 2011 Your alkalinity is too low, get it over 7.5, I would get it into the 8-9 range. why is 7.5 too low? what's better at 8-9? Stability is the key. Don't try to push a parameter out of whack.
zygote2k November 26, 2011 November 26, 2011 I dosed mag not to long ago but it is certainly worth it to test mag. mg probably not an issue. starvation is certainly one of the leading causes of death in aquaria. smaller frags also have a higher mortality rate.
sen5241b November 26, 2011 Author November 26, 2011 (edited) I've fed the H-E-double hockey sticks out of it and I have another brain, Favia, that is looking good. I'm going to look at the problem brain it tonight with a redlight. I think something might be eating it at night. Kinda of a long shot but this is a weird one. I hate friking losing corals. Think I'm gonna levae alk alone. I don't think 7 can be a big problem. Edited November 26, 2011 by sen5241b
sen5241b November 27, 2011 Author November 27, 2011 My bulb is 11 months old. Maybe some LPS need stronger light? Could the old bulb be the problem?
