looking for some fish ideas

[Lenny718]

Why not just make it a salt water tank and call it a day??? This is MR after all and not a fw forum :p :banghead:

Leopard Ctenopomas can reach around 6-7 inches in length. They're ambush predators and will eat smaller fish. Mine's about 7 inches long and 9 years old.

You shouldn't mix tetras with cichlids.

Another interesting genus is polypterus. Some of them can get quite big though.
