i'm not sure what the problem i have with this poor lil loach...he's in my 30 gal tank with three other loaches, I had two and introduced two(including the lil guy) and he's not doing that great..he was smaller to begin with, but even other one has acclimated well(clowning around & eating with the others )..should i keep him in there hoping he gets along better..or put him in my 10 gal(with two small severums and two panda cory's)until maybe he gets bigger?? any info would help..i'd hate to lose him
