Aggressive Molly

[Reece]

Have had my male black molly for 4 months now with a cory also in the tank (65ltr).Aa month after getting these fish I added an angel fish that my brother bought as part of a pair from the lfs, but they did nothing but fight so I took it in. All fish got on very well including the 5 neon tetras in there.

But just recently the black molly has become aggressive attacking the angel fish and the cory. The angel fish' top fin has been hammered and lots of it missing. Is this natural molly behaviour and anything I can do other than removing the black molly?

I certainly found, when I had mollies, that their individual temperaments were quite varied, and I had one female in particular that seemed to model herself on Lucretia Borgia. Not a huge amount you can do to control it, you can't exactly put him on the Naughty Step.

I'm not an angelfish expert, but I think 65l is a bit on the small side.
