IMO focus on true surface or mid-water dwelling fish, such as giant danios, rainbows, and congo tetras. mak sure they are at least 4" to avoid becoming pictus snacks.
and I agree that you should noly get two spotted pictus cats... beware the striped!
ok 2 spotted Pictus Cats.
5 upside down catfish? (reading they are nocturnal, and likes the top) or did I read that wrong.
8 Debauwi cats (Schooling fish for middle of the tank)
and call it a full tank.
?? Maybe add Brushy-nosed Pelco or two, I would have to get some driftwood in my tank, and learn to buy some veggies.
