I think my Acei are breeding. They're in a 46 gallon tank and they chase each toher around in a very tight circle. They're juvies, at about 2 inches, maybe three. I have rocks, and that's about the only place they do that. I've heard they might be getting territorial, but I'm not completely sure.I just tested for Nitrites (0), pH (around 7.8) and ammonia (around .15 ppm.). would the hardness effect this? If they are breeding, do I need anything special? food?
