The last two weeks or so, I've been having trouble keeping Anakin's water warm enough because his heater isn't very strong. I've not seen much of him except during the night, because I've been working long hours, but until today he was eating normally and he'd respond if I touched the side of his tank, so I thought he was doing okay. He's never been very active during the night, and I didn't see how he was acting during the day. But today I've been home, and he's barely moved at all.
