Well so far he's still alive. He was upside down in the sump, now he's right side up, breathing, and looking around when I put the flashlight on to give him a look. Maybe he'll recover.. Way too early to say for now. But he's sitting right side up on top of my bio media in about 3" of water, so he's fully submerged but doesn't exactly have room to swim. I figured it would give him the best opportunity to rest up. I'm hoping he doesn't get restless and try and jump into my return pump or something stupid.
