Dude that sucks ***, i just had one of my healing yellow lab's get tore up today (his tail was almost grown back from being chomped off, 2 months of melefix!!!!!)................well checked on the african tank and he was beat down in the corner something fierce.............no saving him this time............... sucks!!!!
just cause they were in fresh at the lfs doesnt mean they will do fine, they are a brackish water fish. but it still prob would have been the jar, i know they are aggressive, and not nessecery to feed on stuff
