Not sure if this is a correct feeding practice or not, but since we have 1 cricket eating lizard and I buy 1000 crickets at a time (thank you online suppliers ) I just get a handful any time I feel like watching him eat and toss them in (2 handfuls a day maybe?). He's full grown now, and it's just plain fun to watch him stalk bugs. Now that I'm using crickets as a staple I put a calcium powder dish in there, but when I was using phoenix worms I didn't bother. Once I use up my rep-cal I'll be switching to Repashy calcium plus and do away with the dish (if I'm dusting daily I don't see how our single non-breeding gecko would be too terribly off without it). He's something of a bottomless pit, I couldn't tell you how many he gets exactly (maybe 5-10 crickets per handful?) but I keep a bit of carrot in his tank in case there are crickets hiding out.

It's stinking adorable how big his eyes get when he sees the top of the tank lift up, and he whips around looking at my hands like "MANA FROM ABOVE! Where'd they go?!"

Not an expert by any means, but this has been working out pretty well for us. It's technically my boyfriend's daughter's gecko, but she's a little more interested in fuzzy things even with allergies, so I've been doing a lot of the daily care. I like the little guy!
