they started the same size.. same age.. same tank.. same food.. but they are growing at such different rates..
i know with some species the "alpha male" releases hormones or something that keeps all the other males smaller or something (this may be a myth for all i know.. or it may be true.. i dunno)
or do i simply have 2 different species that grow at different rates.. honestly i have done like zero research i just want a quick answer..
and im well aware of how big they get and how fast it happens...
