I have one electrice flame scallop and did not know about its dismal survival rate until I got home and did some research. Now that I have him, I try to take very good care of him.
Flame scallops are filter feeders. I haven't seen mine approach anything (fish, inverts etc.) He mostly just hides in the rocks or in a corner. They are gorgeous, but I do worry about his dying of starvation, which I hear is likely to happen.
Most people would say not to buy them. The more people that buy them, the more the LFS
will sell them. I read somewhere that they don't survive in captivity for more than a year.
I've had mine for 4 months almost. He likes to click his shells together. I really like him and hope he survives.
Thats my input.
