my 2 female fuelleborni are holding eggs, meanwhile the male is terrorizing everyone else in my tank. my male daktari is pretty scraped up on the sides and i watched them lock mouths and brawl pretty bad. other than that only minor scrapes and tiny fin tears on some others, but constant chasing. the fuelleborni are the largest in the tank and the only one who holds his own is my male afra. should i buy a divider? other opinions? if so who should i put in the divided section?
