So I got 5 johanni last Thursday. 2m3f. I know. My ratio isn't the best but that was all the females they had atm. My question is... why did two of the females get browner but the last is still the bright yellow color? My males look gorgeous. Neither one is dominant yet so they both have a lot of color. The browner females are chasing the yellower one around a lot too. What's up with this behavior? I didn't think johanni paired up but could this be the case?
