Color change is related usually to dominance/aggression or camouflage.
Does it affect colour of the fish also because that green terror changes colour in every few minutes.Sometime it is very bright good looking and few minutes later it looks looks dull with white lines on his body.
My convict chose a male bp. Apparently she doesn’t mind an infertile mate who has no parental instincts and barely defends the nest. My Dempsey has been unsuccessfully trying to win her over for a long time.It also reflects receptivity to the female BP. Just because the female chose the male BP, doesn't mean that the male GT won't try to win it over (when the male BP is not paying attention). I've seen my male GT try this with my female pike when the male oscar wasn't looking.
Don't even ask why the female pike chose the male oscar...
I read that cichlids sometimes showcase their colors the brightest to display dominance, but it may not be for every case. Here’s a picture I attempted to take of my female green terror when she was ready to breed, it was hard to capture because she didn’t want to be bothered lolDoes it affect colour of the fish also because that green terror changes colour in every few minutes.Sometime it is very bright good looking and few minutes later it looks looks dull with white lines on his body.


I think it occurs on both.I can see same vertical white lines on my green terror.Is it a sign of female one?
