How many MALE platys will be happy together in a 10g tank? I know an all female tank would be better but I already have 3 males. What is your experience? Would 5 platys be too many? There are a number of forums that are confusing and contradicting since males are territorial but these are community fish.
For a longer explanation why I ask -
I had 3 white cloud minnows and 4 male platys in my 10g tank for ~4 months, no problems. Then one of the platys died - I could not diagnose him (nor could my LFS
) but the other platys never developed any symptoms and have continued to look great.
HOWEVER, now one of my platys is a serious bully. I think the harmony was thrown off by going from 4 to 3. The smallest of the platys spends most of his day hiding from the bully, and will poke around the rocks only to be chased back into one of his spots.
I have debated taking the aggressive fish back to my LFS
but I have also read that keeping them in larger groups, as they prefer, can stop the aggressive behavior. I worry though 4 or 5 males may just aggravate the bullying.
