Are there any type of fish that you can keep in a tank with FBTs? I mean it is a half filled 10 gallon filtered very well and has two FBTs in it. I will do a 10% water change every week.

Maybe some type of goldfish, aren't they from similar areas?
Or Bamboo Shrimp or Ghost Shrimp. Or a pleco to eat any algae.

I just thought that adding something else into the cage would be nice.
