Just got two baby sturgeons yesturday, sterlet and diamond. Put them both in a control bucket. Ph is around 7, water temp is room temperature, no ammonia nor nitrates. Set them in and both looked fine yesturday. Today the sterlet is having problems swimming, spiraling, always upfloat near the surface. Cant seem to swim down or straight. The diamond is just fine. Need help and thanks for your time.
