i have a tiny curly sling who is currently completely sealed off in a burrow. Checked on it today, and the top of the substrate in the jar is MOLDY! That in itself is frustrating, because I thought I could avoid that by nukin the substrate before using it. But now, i am unsure what to do. If the sling is sealed off, possibly premolt, should I wait or should I dig it out, and change all substrate now... Thanks, these little guys are frustrating.
