The sturgeons in there are acipenser baerii (Amur sturgeon), there have never been any reported imports of true "acipenser schrenckii" to Indonesia and its very unlikely for JAQ to source their freshwater fish from anywhere aside from local supplier.
@Rizz Carlton DAT TMII and BXSea kept Acipenser gueldenstaedii and DAT TMII once kept Acipenser ruthenus back in the 2010s. TMII also kept an Acipenser baerii as well. IDK if there are private fishkeepers that kept Huso huso here, though AFAIK SWA may have kept one as their preserved sturgeon is labeled as so.
