I have 2 albinos, one ive had for 3 years and the other for 8 months. They both stop growing at 8inches but the two regular senegals the albinos are housed with are 10 & 13 inches.
my albino outgrew my other senegals very fast in length and width and got to about 12", my regular ones are male though at about 9" each and that was a female
