Oh boy. This horny dude is really causing you all kinds of headaches. And causing himself other kinds of aches. Sorry :/
Yep...thankfully he’s asymptomatic as long as he’s not on substrate. Quality of life isn’t great without substrate but I try to make do by giving him lots of rocks and plants to mess around with until this issue is sorted out. Anything to keep him happy. He’s my special little boy.
