ok, so i got 6 little pygmy corys and i love them! the problem is...so do my other fish. my cherry barb and my harlequinn rasboras are harassing them, i think because they want to see if they are a food source?? they are chasing them once in a while...and my cherry barb is actually bumping them or trying to nip at them and sort of stalking them. will this eventually end? i am hoping that the barb and other fish will give up in a little while- once they get used to the new little tank mates??
