Thanks for the input. I was just wondering what they were. The darker two he clamed they were huso and the lighter one he claimed was chinese
I'm from Europe, so I know European fish...You'd better study your asian bumblebee gobies.
Ok thanks will get a photo when Its feeding timeQuite confident to say it is acipenser baerii ( siberian sturgeon) , need to see their mouth to say for certain

Got it ill have em chonkey in no timeFor the first fish (2nd pic which is the one below the parking lot pic) , it looks to be a Dexter ( sterlet x beluga) but to confirm we need to see the mouth , i think those mouth pics you uploaded are of the smaller fish .
If the mouth is wide , ear to ear , touching both cheeks or gill plates , it definitely is a dexter.
The smaller fish (3rd , 4th , last pic) , is definitely a siberian .
they are very skinny especially the siberians , they dont have the supposed / correct body shape.
believe me i Really hate to say this , but i suggest you power feed them ASAP or they won’t last much longer , keeping proper body weight and nutrition is number 1 priority for acipensers.
We know a hybrid between sterlet and beluga under name "Bester"...Your right it could be a hybrid,the first one..The other Siberian sturgeons are very skinny...For the first fish (2nd pic which is the one below the parking lot pic) , it looks to be a Dexter ( sterlet x beluga) but to confirm we need to see the mouth , i think those mouth pics you uploaded are of the smaller fish .
