All red devils and midas are born grey with stripes. The parents genetics(rr(grey for life), Rr(grey until 7-8"), or RR(red by 4")) will determine when/if they turn red. In flowerhorns, which devils and midas genetics are definitely included, if they have a single dose(Rr) for red they will turn red at a larger size(the fish in question) then say a fish that has two doses(RR) which will turn red at a smaller size. The "red gene" can be expressed as anything from yellow to pure red.haloman02;1606600; said:Your confusing @_@ I dont think anything that you said makes any sense what does doses of red mean and have to do with a Gold Base FH.
