He is pretty small, so I'm pretty sure it's a baby (Its around 2-3 inches). What I'm wondering is that if I should keep it in more water. The guy also said it might drown in too much water. We are planning to get a fish tank for him, but we are not sure about the water level. Also, the guy gave us those log foods for him, and said to feed him those once a day. Other websites say I should feed it other things as well, like worms, fish, and lettuce. Please help, I don't want it to die!!!!
