Be careful in buying little peacocks that are colored up wholesales like to juice them up so people will gobble them up most peacocks will not start to show color until close to 2 1/2 3 inches, in my experience yellows tend to show a little sooner.And depending on the dominance factor I have had peacocks(ngara,regals)that were 4inches that I thought were females and moved them to another tank which they were the most dominanat and they turned out to be colored down males.
