Balloon Mollys

[BlueShinobu]

hi, i just recently bought another balloon molly for my tank, its a ten gallon with four blue mettalic guppys and two mollys (including the one i added) and since ive put the new one in the older one keeps chasing it and running into it, and even a lil bit of nibbling, should i regard this as playing or fighting

They should settle down once one or the other decides who is more dominant

MOllies are a pain for this, well mine (ex ones, gave them away now) are anyways lol

Mollys can be aggressive. It sounds to me like they are being aggressive. Keep an eye on the situation and if they don’t settle down you may need to separate.
