I have only had pleco's in the past, and that was in much bigger tanks. I have a betta all by himself in a 5 gal, and I'd like to add something else to the tank. Being very into bottom dwellers, I'm hoping those may do. I know at this size tank I would need to add algae wafers as there wouldn't be enough for them otherwise. But does anyone with more expereince have any suggestions that could help me decide? Thanks!
