Gl and algae cleaning fish?

oto's are your best choice, a few in fact. they stay small. sometimes delicate when introduced but once established are hardy. clown pleco's or rubbernose/bulldog pleco's are good. regular sailfin pleco's get way too big, SAE's get fairly big for a 5 gallon. Bristlenose pleco's eat mainly brown algae (diatoms) and don't mess with green much. Chinese algae eaters are aggressive and trash in my opinion
