i have a 55 gallon tank with about 1/2 dozen mollies and guppies, 6 cories, 6 small clown loaches, 3 synodontis occellifer, and 1 small bristlnose plecostamus.
There is plent of hiding places and I've never seen any aggression between the fish.
Recently, a molly had some fry. I've noticed that corys will sit in their caves and let the fry pick at them. They are about four times the size of the fry. They do not seem to mind this and it almost looks like some sort of cleaning behavior. They just let the fry work for awhile, and then move on. There seems to be no damage on the corys.
Has anyone seen something like this before?
