So my angelfish started spawning a month and a half ago and I can't get them to stop. I'm pretty sure it's a F/F pair so them spawning isn't going to produce anything and they get territorial towards the other fish. I've tried lowering the heat in the aquarium from 81 down to 75 in hopes they'd stop spawning, but they keep going. Is there anything else I can do? I don't want my angels going through all they eggs when they're juveniles in case I want to breed my prime female later on. OTher than lowering the heat, what can be done to stop fish from spawning, maybe changing the lighting schedule? Right now the light is on for roughly 12hrs, whenever I remember to turn it off and on.
