I have wanted a polypterus for quite awhile, and one is now available to me (my lfs doesnt exactly get them often) and I only have one tank in which there'd be enough room for him, however my young arowanna is currently in it. so I must ask , would I be able to mix a polypterus senegal 1.5" be mixable with an arowanna 2.5" in a 10 gal. growout?
