Thanks for the reply.

I think it might be whirling disease as well. What I noticed when I looked into it is how the stomach near the vent looms enlarged. This is what I noticed in the fish yesterday.

If it is in fact whirling disease, can anything be done, and now concerned should I be?

One other thought I had was that the fish might be full of eggs and that is causing issues. This is because, again, the stomach near the vent looked enlarged.

Any advice at all is appreciated.
