This could develop into an interesting thread.
In regards to mycosis though, prevention is the only remedy as far as I know. Keep humidity low for scorpions that are prone to this fungal infection. For scorpions that are already suffering from mycosis, its spread can be halted or slowed down greatly if humidity is reduced. Juveniles/sub-adults that are suffering from mycosis seem to get rid of it when they moult. So, if you can keep them going and get them to the next instar you should be able to get rid of the fungus. Luckily, young scorpions tend to be less susceptible to getting mycosis anyway.
There was a very interesting article in Reptilia magazine not to long ago on the importance of vitamins and minerals and a varied diet in invertebrates. It touched briefly on DKS type symptoms in tarantulas being potentially caused by a lack of vitamin B or other vit/mineral deficiencies. I know similar symptoms to DKS in tarantulas have been observed by scorpion keepers. The article is well worth a read anyway, and will probably make you rethink the way you feed your inverts. The paragraph comparing growth rates and infant mortality of 2 groups of Loxoscele laeta, one fed standard 'farmed' inverts and the other a very varied diet of wild inverts, is very interesting. The article is in issue 79 of Reptilia magazine. I also have it on my pc if anyone would like me to send it to them.
