Hey everyone. I have a KSB who is a little less than a year old who has recently been surfacing a lot more than usual. He still spends most of his time under the substrate, but he's been trying to find ways to hold himself above it, like curling up on his thermostat. I eventually just put some fake leaves in his tank to give him something to sit on, and I see him up there a few times a day. Is there any reason for this sudden change in behavior? He's always been pretty adverse to being above the soil, even for a second.
