Why not go for chain loaches instead? They only grow to 2" maximum (but very skinny), they eat snails and they have the same kind of personality profile as clowns. I know they are hard to get hold of (I'm trying to get more to make up my school) but they are wonderful fish and ideally suited to a small tank situation.FanOFish said:is it really necessary to keep clown loaches in groups of sixI have a 42gal. with only 10 neons so far, i was hoping to add some angels and perhaps 3 clown loaches. the tank can't handle six??
