Ok, in my tank I have four fish: a Black Ghost Knifefish, a Jellybean Blood Parrot, a generic male Peacock chichlid and a generic female Mbuna chichlid. One of them keeps on biting the tail of the Knifefish but I don't know which one because I never see one of them behaving aggresively towards him. My question is this: is it possible it is the Blood Parrot? My understanding was that because of the way they are genetically bred, they could not bite or nip other fish. I want to rule out that it is him before I decide what to do...if anyone can answer this, that would be great.
