you are right Lorna. i had a problem with those snails and they killed all my turbo snails while back. i have cleaner wresse but i also had a battle with those snails and i beat them. i have none and i know for sure because i used to take them off my snails on the regular bases. but now my other newly set up tank having snail problem that have been killing my turbos. no wresse in that tank, but i'm thinking about getting one because i can't fight those snails alone, too many and killed half of my turbos so far. tomorrow i'll go get another cleaner wresse that eats frozen foods like mine. i have helides. the clam is like 2" i think. how often and how do i feed it by taking it out and how long do i allow him to eat? i feed him in a main tank and i have high nitrates. i thought that was plenty of food, considering that he was in a store for a while under PC lights and didn't have a drop of food, yet the color is good. the thing that bothers me though is that bristle worm is still under my clam and i don't know how to get him out. by the way, he is maxima with blue hue
