I need to find a fish somewhere aroung 3 to 5 inch that swims around the top and mid level area of the tank????? All the other fish that I have stay at the bottom except the Zebra Danios.
marbled hatchetfish?
don't know how they'd get on with the gourami
or loaches though.
probably also need some sort of floating vegetation, plastic or otherwise, but cool looking fish, and reasonably hardy.
Livebearers have nice colours and are active on all the levels of the tank. Cherry barbs are active and fairly docile. Congo Tetras are really nice. Rainbows are nice also, particularly the Boesmani.
