Reidi Fry are born in various shades from black, through grey, browns and even some clear to yellow. Typically, before they reach 8 weeks, they all go "black". They stay dark in color for some time. Typically, when you put them into a display, with colorful decor, and good foods (high in HUFAs etc) they begin to color up.
Hunter is actually Hunter the 2nd

I had another fish I named Hunter from a brood more than a year ago. He/she lives in a display in Framingham, MA now. This lil babe is 2 and 1/2 inches long and is just 4 months old. He/she is actually smallish for the age, but you can tell looking that it was not well fed. He/she took some time to switch over to frozen foods.
