Sterlet suddenly died :-( Has anyone seen this on the bottom of Sterlet before? Wasn’t sure it was puncture wounds by a cat. Just unsure and nervous

It doesn't look punctured. Do you think a cat could have got to it?
Have you considered red blotch disease?

Out of curiosity, what substrate was it on?

Next doors cat has been seen at the side of the pond, but we have a net on top so imagine it would be hard to get to the fish. I have two sturgeon and then mainly koi in my pond. Will need to keep an eye on the other ones
