"Newbie" has been hiding and sleeping all day. He does move around occasionally, at least. (He hides under his heater, or in a rock shelter, or he floats on the surface in a silk plant.) And he DID come out when I dropped his food pellets in, so at least he's eating. I figure if he's interested in food, then it can't be all bad.

He really looks like a wilted lettuce leaf though. He's all clamped up and pitiful looking. *Sigh* Poor little guy. Hope he adapts soon. (But at least I'm not freaking out today, like I was yesterday!).... How's the new heater?
