Bottom Feeder Recommendation?

[babyduke]

I have a 55G tank with 3 yellow tail damsels and 2 green spotted puffers. There are no live rocks, corals/reef. Salinity is 1.02.

What are some hardy bottom feeders and algae eaters that would be comptible in this tank?

1.02 i think is described as bracksih not for ze full marine. Buuut from what i know algae eaters dont do well going into marine and there arnt really any 'true' bottom feeders in marine that are suitable for most aquaria.
