I answered a craigslist posting to pick up an axolotl, however, what they had was this guy (see attached pictures) swimming in water with no land. They said they had him for about 5 years and his "horns" (which must be his gills) fell off about 3 or 4 years ago. They clearly knew nothing about him or taking care of him (they also said he didn't like worms--wrong!). It looks like some kind of tiger salamander, but the tail is much flatter than I have seen before. So my question: Is this a morphed axolotl, a tiger salamander, or something else? Also, I have been taking care of him as I would a tiger salamander, please let me know if I should change. Thank you.
