help with maxima clam

[demonclownfish]

tom, ya the tridacnids depend on light more as an adult but as smaller juvenile clams such as the "micronesia" clams otherwise just being baby tridacnids they rely more on filtering than they do light. and clams dont really reach that point until about 3-4".

I would agree with Tom but would add.....IME if they close up and won't open something is picking on it. Maybe a worm or something else. You don't have long, once those things start going down hill it is hard to stop. I would remove him and give him a good inspection. Check to make sure his foot is still solid and not pulling away from the shell. If there is a gap between the two that is a pretty good indication something is in there eating it. Might try a fresh water dip if that is the case but it might be too late, Staying closed is better than gapping but still not good. If the foot is holding on to something then just leave it, not much else you can do then but hope as the stress of pulling it away is worse.

ok I gave the clam an inspection and it appears to have no foot, I can always remember it having one and im not sure what caused the sudden disappearance. the only thing I can think of are my CUC, they have been flipping the clam over on its side and picking at it im not sure why. I also checked my ALK which is at 9. oh and I never ripped the clam of anything it was attached to its in a very deep sand bed so I dont think it ever really had a chance to get its foot down.

just for the sake of checking I tested the rest of my parameters, nitrate and nitrites are 0, ammonia is 0, phosphates 0, pH 8.4, and alk is 9...thats all I test for.
