I have a 100l tank which i keep mollies and guppies in and one small parrot cichlid cause a friend needed rid of him and he is full grown but still only small. Usually be just swims around and is good natured to the others but recently he has been hiding in a pot a lot and when he comes out he pecks at the filter and nips at the others if they get in his way. However when my balloon molly goes near him he just follows it and what occured to me is it most closely resembles him compared with the others. I dont know if the cichlid is male or female. Is he lonely or am i just personifying him? Should i buy another cichlid and risk it eating my guppies and mollies?Thanks appreciate any help
