>>1)My corn snake stays under his water bowl forever! When I get him out he goes back into his "shelter" again.
If you give him a good hide spot, they WILL spend most of their time in it. Make sure the temps are OK where it is hiding (some snakes are so stupid they'll hide instead of thermoregulating meaning they'll cook in their hide spot!) He's "safe" in the hide spot, not hungry, etc., so he has no reason to come out. That's what snakes do.
>>And also, my corn doesn't move much. Is this ok?
That's typical - especially for young ones. It probably moves when you aren't around scaring it - especially at dawn and dusk. As long as it is eating well and has good muscle tone when you take it out, I don't read anything here that should cause an alarm.
>>2)I bath my corn about once a week. When i put him into the water and let him swim around, I noticed that every time he gets into the water, he defecate in it, ALWAYS.
>>Is this normal?
Yeah. That's normal.
