Heh Lids
Ok when was the last time he ate and can you post piccies of his current state??
all you can do is wait and watch.
I personally don't think it's fungus, it looks more like dead tissue sloughing off from around the wound.
fungus more looks like white tufts of cotton wool, like a fluffy cloud attached to your axie and it spreads fast.
May I ask, is your axie in the fridge?
thanks for the piccy update, poor thing Lydia all you can keep doing is fridging him with daily dechlorinated water and keep offering a worm daily, you can leave on in there for him for an hour and if its not eaten just remove it, he may eat whilst your not looking!!
Hpe he gets better soon, your doing all you can do, fingers crossed!
