I recent rescued a sad little chihuahua, but to be honest, I'm mostly a reptile person. I professionally breed a very rare species of aquatic salamander called the axolotl. (they've recently gone extinct in the wild).
These ones here are my personal pets. Left to right there's Lefty, Jelly, Lucky & Svejk. (the last one's a Czech name, it's pronounced like Shrek, but with a v sound where the r sound is)
Some of them have an extra gene that allows them to glow under blacklight. This is a juvenile in my hand underwater with a uv light on him.
They lay eggs on the plants in their tank about once a year. You can see the white balls on the plants that the albino (Lucky) in the photo has just finished laying. (it looks like they're all trying to take credit for them though lol)
They love people too. They'll come right up to see you as soon as you make eye contact with them. And they can recognize their owners vs. strangers.
The proper name is axolotl, but a common petshop name for them is mud-puppy because they're so friendly. (a 'true' mud puppy is technically a different species though).
