Hi. I'm newer to the fish world, all I've ever kept is betta. But, I bought a tank, roughly 28 gallons big and my friend gave me 3 mollies.( 1 adult female, 2 juvenile females) Then, the adult female had babies, I have the eleven in the same tank but in a hatchery net, over time, I've added new fish and a pleco, but recently, the adult molly fish has become aggressive, chasing the other fish, she looks like she's fin nipping, but I can't find any torn fins. I don't know why she is so agressive and I don't know what to do with her. I don't have another tank to put her in at the moment.
All advise is welcome.
