I have a yellow wrasse that doesn't look too well. I don't remember how old it is but I don't have it that long, maybe a year or two. I got it full grown.
For the last few months he is having trouble swimming. Wrasses don't swim well anyway but this one seems to have a tail that is semi paralized.
He looks good, eats and gets around but fish, like people also develop other diseases and maladies that we can't see on their skin. We usually see spots, discolorations, fungus, fin rot or scratching but we often forget that fish also have internal organs, a circulatory system and a nervous system that are subject to disease just as we do. When we get sick, most of the time you can't tell just by looking at our skin. As a matter of fact, you can rarely tell just by looking at our skin. (unless we have an arrow sticking out of our head)
Fish also sucumb to internal problems and possably auto immune diseases even cancer (except sharks, they don't get that)
I would also imagine that fish can get heart attacks and strokes. Those things are just things that can happen to any animal with a heart and brain.
If this fish dies, I will not autopsy it because I know it is a nervous system problem and an autopsy will not reveal anything that I could see with "my" primitive equipment.
