This might be an odd question, but does anyone know how wide the para pleco gets? Length is less of an issue. (Obviously, having ropefish means I am ok with fish that will grow quite long.) But I have seen some plecos in pet stores that have such huge heads, they almost look like shoes in a fish tank! I would be fine with a 9" pleco, but if it gets over 3" wide, I think it will look out of place.
