When I was young, we had Flame Scallops in my parent's tanks. I love their vivid color, but apparently they just don't fare well in captivity. My first one was consumed by my Coral Banded Shrimp. Finally, I was bored with all the green in my refugium, and since these clams are not photo-synthetic, lighting wasn't an issue. I put it in there, and it remained quite content living in that predator-free zone for about a year. I fed phytoplankton every other day, which it filtered from the water column.
