i know that shovelnose sturgeons are coldwater, but could they live in room temperature? because i am planning on getting one and having it share a (divided) tank with my west african lungfish.
They are listed as living in water up to 68 degrees F. maximum, at that temp. they need higher O2 levels. the two that I see living at up too 76 F. are the Gulf and the shortnosed sturgeons.
Yes keep a close eye on the temp. but you should like these guys because I once saw them at a public aquarium where you could pet them and they were very freindly and felt like leather so if you want to pet your fish that should be fine with it.
