If an established cichlid is "invaded" by a new cichlid then they will be aggressive towards the new fish. When a fish is by itself it will claim the whole tank to itself and when the new fish is introduced, it will defend all that territory. Males are usually more apt to this, but a female will defend territory as well for future egg laying
i understand that. the new fish (female) is the one in charge though! wth?
she is nearly twice the male's size, but i never would have guessed this. i've been watching them for about 20 minutes each day this week and all i ever see is when the smaller male comes about she's chasing him around the whole tank. more so now than at first. it even looks like he has a couple minor scrapes on his head, probably from hitting rocks and plants when being chased. it's been 1 week sunday since the female was added, how long till eggs will be laid? or how do i know if they will never pair up and mate? could the male being smaller make a difference?
