I'm trying to migrate my RFA to a new tank. He is wedged WAY deep in this rock, and I'm pretty certain that if I tried to split the rock, I'd crush him. So right now I have the whole rock hanging upsidedown over the tank, and he's drooping pretty low, just barely touching the top of the water. It's been about an hour now, and he's not showing any signs of budging yet. I know that these guys can stay out of the water for a while, but I don't know how long I can leave at least the foot portion out of the water before seriously damaging it. Thoughts?
