Our new pet

This is our new pet salamander!! He was an impulse buy at the mall. We thought he was too cool looking to resist and the guy said they are really easy to take care of, only feed him a couple times a week, replace part of the water every couple weeks, and we can even treat him to a few crickets or worms if we find any. Yummy! We already had the tank and the decorations so it was a really easy set up! I think we've figured out that he is a tiger salamander and that he is still in the larval stage so we think when he becomes an adult he will lose the external gills around his neck and then will need more of a land environment. He obviously lives in water now but he does breathe air too; he'll come up every once in awhile and open up his mouth and take a big gulp of air. He gets excited when we come to feed him and they are as harmless as a goldfish so no worries there, he's as friendly as can be! Now we just need to think of a cool name for him....any ideas?!`
