Hey there, I'm new here.
I recentley bought a new tank (60 litres)
I have some Mollies in it, 2 of them are black, female and male.
For some reason, the black male molly keeps attacking my other fish,
90% of the time the 4 Gourami fish i have.
There is a real chaos since he started, the Gourami (twice bigger the him) keeps swimming away and hide, and I don't want to allow this stress, especially because they are all new and still acclimating.
I'm posting it here cause my guess is that they are trying to enter the breeding world (he and the female black molly) and he wants to make sure no one disturbing. Any other ideas?
