Hey Tara,
For my first gecko i got a pair of Thick Tailed Geckos!
They are a great gecko, and absolutaly love em to bits
sooo cute when they hunt down their food.
Tank Size: I keep mine in a 45cmx45xcmx45cm but you can fit a pair in a 2ft long x 1ft wide x 1ft tall tank easily.
Food: Hatchlings should be eating pin heads whilst adults medium sized crickets.
Substrate: I think the URS Red Desert Sand is a great substrate as it hardens, and makes great ways to build burrows !
On the warm side, i keep the temperature around the 28 deg. area, then the cool side room temparature, feed them every couple of days, and also spray them everycouple of days, try to spray down the sides of the tank as they will drink the droplets, mine are currently breeding with 2 eggs already in the incubator, these geckos are a hardy species, and a great first gecko!I may even be selling a pair of unsexed hatchlings when they hatch at around $140 ea(they cost $150-$180 over in WA) So if you need any more help with geckos just give me a PM and i'd be happy to help
Thanks,
Chris
