My big oscar has calmed down during the day. he just chases the other red tiger oscar sometimes but i think it is because my albino tirger oscar is a female and the 2 red tiger oscars are male. Will this help when breeding later???? like competion for a female or will it cause even more agresstion??? and i have noticed when i come in after liveing my lights off for a few hours after dark and turn on a hall light so i can see what he is doing w/o disturbing them and he just opens his mputh half way and chases the other fish. Is this normal???
