Well, yesterday I went out to my lfs and i bought an adonis pleco that caught my eye. Not surprisingly, when I got home I learned that I should have researched before buying. Exactly how big do these get and what tank size is the min for these guys? I know they get humongous so I was just thinking about a huge rubbermaid. I've looked over a bunch of sites and they range from 500 - 1000 gallons. Thanks!
