Any with the Minn. Wild colors? J/K. I wouldn't mind a Zebra, but my Otto does his job, so I would go for a shoal of them. Singularly, I would keep a Bristlenose. I am, of course, a little too conventional for all y'all!!!
i like my zebra pleco. even though he hides all day . people are always intrigued as to why i payed $60 for a fish that i never see. but they tend to stop after they see him.
it would depend entirely on the size of the tank. if i had a huge tank or pond an acanticus adonis or histrix would be cool. if more limited in space but still good sized tank it would be liposaurus or any pseudacanthicus. with a small tank it would be one of my L204 or this little guy:
