So I have a 200 gallon and really like the upper jaw polypterus.... I have a Palmas Polli. Can you guys recommend maybe an additional bicher or 2 or 3? It is going to be mainly bichers. Currently I have just the polli. I do know I would like a more active species but thats not a deal breaker... anyone have any ideas of what other species I should add... Ive did alot of research, but I would like other opinions on the matter of why they would choose 1 over the other.
