This is a mystery... All day yesterday he was clear, nothing on him.
He seems fine - swimming & eating normal.
This thing shows up between his pectoral fins - today there is a tiny bit
of something there. I have to stress it's NOT connected to the gills -
I keep having people say that.
It does not look like anything I can find on the web.
It is ONE thing, no tentacles or Y shapes (like anchor worms) etc.
It falls off & then grows/comes back?
It's really short - like 1/4 inch - not long & flowing like the picture above.
