I have a 280liter tank with just 4 angels in. they seem to have developed into 2 groups one black, one white and are always at war with the other. 1 of the angels started laying eggs while another seem to protect them and follow behind. this has happened 3 or 4 times now (they eat the eggs after a few days)
I know egg laying can cause fighting, but its now been a few months since the last laying and the fighting has got to a point where they are hurting each other, 2 of the angel fish live in fear hiding at the other end of the tank (the spot where they lay eggs) then daring across like a rocket to attack, really nasty. they have not damaged each other yet, but is only a matter of time!
Any idas how I can stop this, or why this is happening?
