I know cresties can drop their tails, but my boy is missing just the tip. His cage is fairly simple - climbing vines, a hollow rock hide, and a potted plant. Substrate is reptiearth (?)- that brick of compressed dirt. There's not really anything he could have injured himself on, so my best guess is that he bit his own tail. Has anyone ever had their cresties do that?

I already put antibiotic on his tail, but while I was moving things around to get to him I saw one tiny silver bug burrow into the dirt. My room is in a basement so bugs aren't a surprise or anything, but I'm worried about if they might be harmful to my crestie. Especially with the tail injury I'm wondering if I should pitch the substrate and just use paper towels for now (but then what do I do with his plant? He really likes hiding in it).
