I am Freaking out! I have had an Ultra Blue T. Maxima for about 2 to 3 years . Last week it jumped ship from the rock it was attached to for the past year and a half. This is the second time in 3 years he has done this. I put him back hping he would get comfy again only to find him slowly over the past few days failing. I then saw my coral shrimp nibbleing on his mantle one night, then a hermit crab. At this point my prize clam is looking quite ill, his mantle is no longer fully extented his intake siphon is kind of open and his exhaust sipon is open and not fully extended. I think this is the end of this beutiful clam I have re perched him high up in the tank where he is less likly to be disturbed. Is there any hope? Can a clam recover from this damaged mantle? If not do I leave it in the tank and risk polution?
