Illness/Sickness: Axolotl with a lump

[Tyliai]

Hello,
So situation here is like that. We got this axolotl from previous owners. This axoloth has strange lump near his gill on a side of his head. Story behind this that might be helpful is that previous owners wanted to show this individual some wild life and gave him fish from a outside pond and after a while after axolotl ate the fish that strrange lump appeared.
We were wondering if this might be cancer or parasite or mabe something else and how to treat it if possible.
I ve added some pictures
I appreaciate any suggestions.
Thank you

I haven't seen this before. Maybe take here or him to the vet. It could possibly be a tumor. Vet is the safest and is the only thing to do. Otherwise I don't really know.

I agree with Aristole, vet would be the best option.

Yes - this needs vet input.

I have once fed a piece of baby shrimp to my axie and it scratched her throat creating a bump lump of inflammation. In worst case scenario your axie has a tumour else it is a large inflammation. Poor buddy the gills are so shrivelled now.

Just wondering how your axolotl is doing. Hopefully you could find a vet who could help it?
