I already own a senegal and my LFS just got some polypterus palmas in which I've never seen around here and I ordered a delhenzi. Think i should get more for my 75 gallon?
Forgot to add that I will set my 125 up when i get the space. The bichirs will share a tank with a african leaf fish, a senegal bichir, a firemouth, a severum, and a eclipse catfish.
All the species you have get about 12". 5 would be fine in the 75 and once you get the 125 you might be able to add something slightly larger like an ornate.
Is the leaf fish Ctenopoma acutirostre (leopard ctenopoma) or something different?
