yeah i think i may have stunted his growth along with my 3 plecs ive had for approx 3 years and are still only about 2.5", he was kept in a 18x12x15 for the first.. almost 2 years, as i set up a tank and bought fish before i had a clue what i was doing (my bad) he was only fed once every 2 or 3 days on cichlid pellets
he is now in a 100cm which i know is still small but since he went in he has about doubled in size approx 4 months ago. and is now being fed probably too much on a mixture of, cichlid pellets, dried tubiflex, dried bloodworm, flakes, some kinda goldfish sinking pelltes, he basically will eat anything
