Hi guys, recently my 125 gallon tank had cycled so yesterday I added 2 pretty big angelfish and 2 small discus I've noticed my 3 6" clown loaches constantly chasing the new stock, especially the angels with their mouths wide open like they want to eat the angels tendrils (I think thats what they're called). I thought clown loaches were supposed to be peaceful community fish, whats going on?
