Just noticed two of my multis were licking jaws together last nights. I've heard this can mean aggression but also breeding and a pair of mine just started to breed so that can't be a coincidence. I have no idea what to do with this so any advice or knowledge would be helpful right now.
You don't really need to do anything, unless one starts getting bullied. If they start breeding, great! If it's two males fighting over dominance, depending on the tank size, you may need to rehome one.
Well my tanks a 55 gallon with about half of it multi territory. I finally see some fry so now that the breeding began I'm gonna get some cyprochromis. My tank does seem to have an abundance of males though. Would getting more shells also help soothe the aggression?
I'll try that then, only one pair is breeding so far but I'm seeing one of the smaller few swimming in and out of the shells with the largest male sticking close. Might have a second pair getting in the mood
