| Hey weezie. i have a pair of blueys and they dont eat every day either. I generally feed them every second or third day. Sometimes they eat it all, other days they'll leave half of what i put out or ignore it all together. Just depends on how hungry they are i guess. They generally dont drink a lot, except when they are coming up for shedding they go off their food and they drink more than usual.
There's a lot of advice out there on temps, depends where you are and where they've come from. They're pretty much bomb proof in the wild and can cope with a wide range of temps. I generally keep mine between 25 and 30 although i've let them cool off this winter so they're tank is at about 20-22 degrees i think.
I have a book 'keeping blue tongue lizards' that i got from the pet shop here for about $9, very good investment. I also got a lot of help from the bluetongueskinks.net website - do a google for it.
Good luck with your little fellas! |
