Left lake sturgeon - Mississippi and right Amazon river habitat?

Just lake sturgeon Accipenser fulvescens (how many, 2+?) or other species too (more labels ...!)?

@Kifaru Bwana It's one tank

@Moebelle, OK ... thanks. A bit of curious mix then.

I would have much preferred separate large tanks for either presenting their individual habitats.
Lake sturgeon is not exactly a very abundant species and much affected by pollution in the Great Lakes basin as well as in the major rivers like the Mississippi, St. Croix and Minnesota. The species is also on the IUCN Red List unfortunately.
