So I have a 150g, about 23 all male hap/peacock about 3-4" with a bristlenose pleco. I bought an albino longfin pleco about 8 months ago and it came as a baby, only like 1". For fear of getting eaten, I have put it in a 6"x6" fry net cage in the aquarium to grow it out first before putting it in with the rest. However, its size has barely gotten any bigger while all my other fish continue to get larger. Is it because of the constraint of the net cage that keeps it smaller? I feed it only wafers about every other day. Should I try to feed it more protein?
