Awesome! I kept one of those as a pet for years; bought it from a local pet shop. We also have them living wild around here, though I have only seen their larvae and eggs in the vernal pools. The egg masses are huge compared to the sals (about the size of a tennis ball in some cases!) and it is amazing to know that this egg mass came out of a few tiny sals!
Sal was an awesome pet. We fed him mainly crickets, but also some nightcrawler worms. One key point is to make sure that they stay pretty hydrated; this means moistening the soil they're in, cuz they do not like to go into actual water usually. But this is you I am talking to; I am sure you already researched them!
