I am wondering if anyone has had this happen? he is just beating them up and has killed one . now he is working on the other one. He is leaving the fry alone . I need to mover her but i dont have a tank ready. what to do?
By nature aquarium strains tend to be less aggressive. Aggression in Mollies is not seen as desirable trait, so it has been bred out as much as practically possible.That is so strange. I keep a 55 gallon with about 25-30 black mollies and I've never seen any aggression.
Wild Male Mollies are aggressive only to females. The recommended ratio is 3 females for every male---then in a large tank.
Subrosa is correct. Tank bred mollies are very a very different fish.
