I've been doing a lot of research in trying to find fish that could be compatible
(already had to rule out the needle nose gar...even though its one of my favorites. Same with the black ghost knife)

Here are the fish/invertebrates I'm looking at (any feedback is definately appreciated)
2 Ctenolucius hujeta (freshwater barracuda) which grow to be about 10 inches
3 Ctenopoma acutirostre (leopard fish)
2 Pantodon buchholzi (African butterflyfish)
2 African Giant Filter Shrimp Atya gabonensis - grows to about 4 inches
1 Hammers Cobalt Blue Lobster
(Procambarus sp.) - which grow to about 5 inches
and maybe a Cuvier Bichir
(Polypterus senegalus)

Would these be good tank mates?
Along with the rainbow shark I already have

if you didnt have any of the other fish, an awesome choice would be some tetras and DISCUS

no >.<
