Not having enough coverage in his tank will stress him out, I think you need to do a bit more research. These guys do not sit around in open fields in the wild, why would they feel safe doing so in captivity. They need cover!
As for your other comments, I work in rescue, rehabilitation and education, I have seen far more than you can imagine, have seen animals with "dead tails" die within hours because their irresponsible owners didn't feel that they needed to see a vet, have spent my time, energy and money to get animals healthy because Irresponsible owners thought they knew what they were doing and didn't listen to the advice given them.

I have a very hard time believing that his tail healed up, but miracles do happen... he will still have the toxins in his blood, but you don't want to hear that.
