Gotta be more specific...most people think pleco when they think sucker fish and usually it's the common ones being sold, not the dwarf types...they get huge and poop a lot. Chinese algae eaters are on the "no-no list" too.
As for having tankmates we don't usually recommend anything but a snail or possibly shrimp in a 5 gallon, 10 gallons in the minimum for having tankmates so everyone thinks they have enough room...wait, the betta still tries to take over!!! :)
