Illness/Sickness: Possibly sick Tiger Larvae? Does anyone know?

The other day I was at a bait shop when I saw an adorable little waterdog. I decided to rescue him from being bait, and as luck would have it, I already had a unheated glassbottom tank set up! After I put him in, I noticed a few things about him. He has a few bite marks from being kept with others, including a missing gill. But what really concerns me is that he has a few white spots on his side and large black watt looking things on his neck. He seems happy and healthy, but I am still concerned. Can anyone tell me if I should be worried?

Maybe fungus? Not sure because I have never kept waterdogs before, maybe a more experienced member can chime in.

They are essentially the same as axolotls but they eventually go on land. And I’m no longer worried about those. They don’t seem to be bothering him and they don’t seem to be growing. But oddly enough, they are hard like fingernails. I found that out when I had to take him out to put him in a tea bath and he started jabbing me with the one on his chin
