A few posts ago, I mentioned that my husband bought a fire belly toad with brown spots on both his sides and around his eyes. Nobody has replied...so again here we go :

When I first saw him at the pet store a few months back he only had one brown spot and the guy there told me it was 'just a sore'. I didn't want to get it though. But my husband didn't know about this and now we have it here.
What am I to do with it?
I really need to know if I should just get rid of it (in a humane way like the vet) or what.
If someone has any idea??-I know colchicine is keen on stuff like this...do you know what this is or what can be done about it buddy?
Thanks
