Well despite me saying my pleco is harmless i just witnessed him attack my polys 3 times and try to suck on them. I am going to get rid of him sooner or later. I need suggestions on south american algae eaters that are going into a tank with small to medium size SA cichlids (and of course my lovely polys) Anything helps i need the info ASAP because i need to have my tank all settled in before i get my apistos. Thanks in advance Dr.B
