Yes! Get a little one. They're super peaceful. They clean the tank and are fun to watch when they stick to the glass.
I love, love, love our pleco. He's actually not doing too well and I will be super sad if we lose him. We have 2 50 gallon tanks and a 10 gallon tank and each one has a pleco. Dd's 10 gallon tank has a little albino pleco (she has glo fish) and it's the most awesome thing ever!
We also have a cat fish in each tank. Bottom feeders for the win!
Dude, I had no idea owning goldfish was so complicated. When I won mine I plopped them into a bowl together and cleaned the thing by hand about once a weak. Obviously it worked for them because they lived for like 6 years, but it makes me sad thinking that maybe their life wasn't as comfortable as it could have been
