Advertisement Hello everybody. I got my B. Smithi sling about a month ago, and it just had its first molt. It is about 1/3" right now, and about 3-4 days before the molt the usual black spot appeared on its abdomen, so I thought everything was fine. Now it molted, but that black spot is still there, the old skin is too small for me to see everything in detal, but it looks like only the bottom part of the abdomen came off. I kept the humidity around 70-80% and sprayed like every day after the appearing of that black spot. Anyway the spiderling itself acts normal, runs around like before, but again, still has that black spot. Is it a bad molt?
