Angel Fish Bullying

[nickward_uk]

Ok, so perhaps bullying is a little strong, but I currently have three angel fish in my tank and there's a definite pecking order, and one of them is starting to get maybe a little bullied. It's nothing serious at the moment, the ocaasional nip, the odd chase-away - most noticable at feeding time, and the bigger angel is just getting bigger, whilst the smallest is growing much slower.

I'm thinking of re housing one of them - either the bigest, or the smallest - not sure yet which... how will one fair on its own? does it mind being solitary, or should I keep them together in the hopes they'll get on? My "spare" tank, which i've stripped down and just started to cycle again is only 60l and I reckon this would probably be too small...
