Sounds like an odd question, but I've got four discus in my tank at the moment, and its been chaos lately as two of them have paired up (methinks) and started shimmying and chasing the other two around the tank.
Seems like i have a great situation, except I'm almost 100% sure all four of my discus are female
How do i stop them from showing breeding behaviour, or is the only way to split the two?
