Not cotton not ich then what

My purple firefish has to (one larger than the other) organisms attached to it.
They are anchoured by a white spot or mouth then the rest of the "body" is opaque/white in colour. The body is oval in shape but gelationous and appears to move with the current and of its own accord whilst always staying anchored at the "head" end.
The smaller growth is 1mm long the larger 2-3 mm long

any Ideas and if I can catch him can I gently scrap it off?

If you can catch him all that is needed is a freshwater dip it will kill the parasite and the fish will be just fine.
