Need some help with a sick Killifish (Nothobranchius Rachovii)
He's got a lot of small white worm like things growing all over him. Started off about 2 weeks ago, the 'growths' were quite small but they've gotten larger since then and he looks absolutely terrible now.

Not sure if it's a fungus or worms? They don't seem to be Anchor Worms. Tried searching for further info, and the closest I've got is "Dermosporidia", but I've never seen it so severe before.
Tried adding Salt, and another medication which contains Methelyne Blue, but it doesn't seem to be working.

He's the only one that's sick, all other fish are doing fine, and he's been in quarantine for the past 2 weeks. Water parameters are all ok - I have shrimp in the tank which are doing well.
