Water Turtle (under water)

[homic...@gmail.com]

Hi All,

I was in fishstore couple of days ago and I saw a couple of turtles in
their tanks swiming around. (owner said they are fresh water turtles).
Those where not like Red Ear family kind of thing. They were under
water turtles (breath under water and won't come out). Does anybody
know what family are they belong and are they hard to keep?

Thanks in adnace,

Homer
