Need bottomfeeder for sword tank

[kitties1]

I have a brackish 10 gallon tank for my three swordtails. I would like some type of bottom feeder to scavenge the bottom of the tank for debri and uneaten food. My other tanks have corys and plecos, but i have read that salty conditions are not good for these guys. Does anyone have a suggestion on what type of critter would be good? Also, I do not have a lot of room, so larger species are out, looking for something small and compact if possible. Thanks for your reply.

some type of small catfish would do good. they seem always hungry and wont harm swords. gl
