if u feel like spendin 25 bucks u can get a nice looking pleco...
most plecos r hardy and most get around 6in..
look in the pekolaita family dont mind my spelling but they stay relativily small..
but they basiclly all do the same thing some are carnivouris but yea theres only a select few that are really sensitive to water conditions so basiclly....if u have the money get w/e u want jus make sure u do some talking at ur lfs with some one who knows there fish....
personally i think brislte nose and rubber lips are hideous..
just make sure u dont buy a common plec or a sailfin..they get huge///
search the web for a snow ball plec, green phantom,blue phantom, tiger pekolaita and blah, ur options are not limited..
alot of people wont type out pleco because they think their pleco will die if they do. its not common on mfk but i have seen other boards never use pleco, and either type placo or pl?co.
