I'm really upset... I had a baby gold maxima with awesome colors that I got about a month ago, that just died. 
He was about 1.5", and I fed about 3x a week using the bottle top method. I had him placed on the sand, and I have a pair of 250w 20k halides (90g tank).
He was doing ok until a couple days ago I noticed he was gaping. I thought maybe the lights weren't enough for him, so I moved him higher in the tank... obviously it didn't help.
I have 3 things that I think might have hurt him: like I said, maybe the light wasn't enough.. I thought he would be ok since they rely so much on feeding.
Second possibility: I just got a refractometer and discovered my sg was off by 4 points - 1.030! I have been slowly lowering.
My third suspect is pyramid snails. I have a derasa in my tank that has grown very well, and I know I have the snails. I would check the baby every time I fed him, and would occasionally find the snails on him (usually none or 1 snail, but the other day I found 3).
Are these snails my clam-killer? Obviously it would take less snails to affect the baby than the derasa.
If it is the snails, does this mean I'll never be able to buy baby clams?
Here's a pic when he was happy... he made me smile, I felt like a proud parent. I'm so sad now.
