most of my fish have chunks and nips of their tails bitten off.
i dont know whos doing the biting.
i have:
1x balloon molly
1x ghost knife
1x angel fish
1x electric yellow cichlid
1x dwarf gourami
1x golden gourami
1x loach
1x gourami with horizontal line
1x female fighter
2x glass catfish
2x golden panchax killifish
2x johanni cichlid
2x gudgeon
2x shrimp
3x bristlenose catfish
3x rainbow sharks
3ft.............
 
That is a hell of a lot of fish, by the sound of it, i believe it is the electric yellow cichlid and the johanni cichlid. Cichlids should definitely not be placed in a tank with community fish such as the molly and the dwarf Gourami.
Cichlids need their own tank with specific water conditions, they can be very very territorial and aggressive.
I would get them out, and possibly the sharks, depending if they don't have enough space.
