2 neon swordtails
2 harlequin rasboras
2 sunset platys
1 albino cory cat.
What can I do to stop this?
hey there I think that you might have to do some research on your fish to see if the have to be in large groups. Some fish start acting aggressively if there are not enough of that that kind of species in your aquarium. I would look in the tropical fish profiles above and read about all your fish. After that I would go and google them too to look at other profiles of those fish.
sorry about your looses my friend good luck!
