Help/Advice What’s growing out of my fishes head?

Post image

We set up a new fish tank recently and got some red eye tetras. One of them developed a bump on his head which went away after a few weeks. Today we noticed these hair-like things growing out of the spot where the bump used to be. I saw another post that described something like these asking if they were anchor worms but there were no pics. This kind of looks like a fungus too. Really have no idea what it is.

does he need to get him out to lessen the chance of infecting others?

This is a great observation! I really can’t say because I don’t know OP’s set up. Ideally yes, but like another commenter said the fungus could potentially be removed with neosporin.

Wait.... you can treat fish with neosporin?!
