Alright so this is my MM B. Smithi.. His butt just recently started going bald and I was seeing what looked like little green mold in his tank.. But I just saw him cleaning himself and noticed it was under his spinnerets.. What is it and why is it all over? It was all through his water dish as well. Also.. Is his butt going bald a sign that he will be in tarantula heaven pretty soon? I don't have the heart to see my baby go!!
