Wizill has one. I have a pump in my dish from a desktop fountain. If you use anything other than the actual reptiflo, make sure it has an adjustable pressure. Luckily mine does, saving me a trip to the store. Works extremely well, humidity is constantly great. Need more, and adjust flow accordingly. Nice!
Both of us have pics of it in our albums.....
Xaero doesn't seem to mind the pump (it's quiet and I found that if you place it in the middle, the vibration all but disappears), I've seen him drink, but have yet to see him soak. Maybe be does it while I'm asleep, but I've never caught him doing it.
I highly reccomend these little pumps. Most have suction cups for feet and stay put very well.
As far as him being exceptionally active, unless you've been cleaning with bleach and not rinsing well (he would most surely try to get away from the smell of cleaning products), or he doesn't approve of his hides for whatever reason, I probably wouldn't worry about it......he's probably hunting or just likes to move around. If he's giving you trouble going to thawed, you can try stun/killing first,or do the no-no and feed him in his cage where he will be less stressed. I use a feed box with astro turf on the floor. He won't eat in the box without it. Apparently having something familiar to lay on is a big deal to him.
Have fun learning what your critter wants............ :?
