Callamanus Worms - Can Axolotls Get These Monsters?

[Emberaria]

Okay so recently I have discovered that my 29 Gallon Tank with my Tropical Fish is loaded with callamanus worms which have led to NUMEROUS fish Deaths. It is said that you should wash everything that your fish come in contact with. Unfortunately I have been using the Same 5 Gallon pail to do water changes with my axolotl Tank. Now I'm worried about whether my axolotl has these worms or not.

I have bought Levamisole which is a goat dewormer to get rid of these nasties in the fish tank... and Im not sure if I should or even CAN use it in my axolotl tank. Ive never heard of an Axolotl getting Callamanus worms...

Someone please give me some advice!
