Pictures included, is this a fluke?

Got this after a 5 min freshwater bath of my wrasse that’s been hitting his gills on the rocks the past few days. Looks like some kind of bug on the right. Is this from him or something else? It doesn’t look like a fluke from what I’ve seen, what is this and is it bad?

Not a fluke, some sort of arthropod. I’d say a copepod. Some of these are facultative fish parasites, they live in the tank, but act as micro predators on fish. Other copepods are harmless, while a few are obligate parasites and are never found off the fish. This doesn’t look like one of those. My guess is this is one of the harmless ones.

I'm going to start promoting the idea that folks all buy a cheap microscope - I got one for my cell phone that cost $16 (grin).

Looks like your Microscope recommendation already took off ;Woot
