Solo bottom feeder

I have a 20 gallon high with 7 glowfish. What kind of solo bottom feeder can I get? Its gravel substrate btw.

 

You could get ghosts I guess. A 20 gallon high isn't much space for bottom feeders

 

What about a single cockatoo cichlid?

 

You know you could do well with 6 kuhlI loaches!

 

It might be a regular. Dimensions were something like 20×12×18

Are you sure those are the dimensions? If so, then it's not a standard 20 gallon high. Then the only bottom feeders I'd do are some shrimp and snails.

 

24×12×16

 

And you have glofish tetras?

 

Yes

 

I think a small dwarf cichlid like the cockatoo cichlid as mentioned.

 

It's not really a bottom feeder from what I read. Or am I wrong?

It is.

 

Ok. Thanks for the help
