Hey Guys i wanted to get two males to 4 females in a 30 gallon tank. Is this enough room or would two breeding pairs need more room?
2 pairs might work but I'd skip the extra females. they're quite territorial IME
are they domestic cacs? or wild caught? I would try it, but have a backup plan. I have had a few cacautoides that are just focused on murdering rampages and some that did fine in large groups.
