I want to add a bichir to my 125 gallon tank but im not sure what kind. I currently have:
-12 inch fire eel
-8 1/2 inch shovelnose cat
-13 inch gar
-7 inch severum
In 2010 there were some changes to Bichir literature not many people have been aware of. The following are described species only. The giant variant of P. senegalus has now been described as a new species, a subspecies to P. senegalus, forming the Senegalus complex. Both are now: Polypterus...

There's also another chart somewhere... I'll try to find it. ETA - same thread as linked above, on page 4 the way my posts show right now. Big white chart with various general sizes for CB, WC etc.
I think the Sen will stay too small for the other fish, which is why kno4te didn't recommend one.
