Its been a little bit since I got a response on this post, but I'm glad i did. I have come a long way in figuring out new "methods" and whatnot when it comes to my crested geckos. Here, I'll answer MY OWN questions, and you can tell me what you think, ok....
cleaner/deodorizer-quatricide TB works awesome for me!
Don't perfer CGD- I agree with Laura B completely.
laybox substrate- I use exo terra's "forest moss". works awesome.
humidity source-misting, and this contraption called a humidimat does the trick for me.
vit/nutrients- Don't use many. I dust crickets every other feeding, and then feed them thier cgd mix (read further)
As far as for the baby food- I was reluctant when I bought the male because the seller was feeding him the baby food and rickets exclusively, and he said that was a good stable diet. Last time I buy anything from him, needless to say. After lots of learning, I have them on my own suppliment. I combine fresh organic fruits, CGD, and some water and blend it to make a nice puree as thick as maybe a milkshake would be. they get this every other day, and on the days they don't, its crickets dusted with calciu powder (with d3). I do have to say, though...they were losing weight like you said and havent bred yet, and I was worried, but I think things are doin better now. Thanks for all of the responses. Keep posting so I can have your input and oppinions. JUST TO SPICE UP THE POST- maybe, if you just have general advice on subjects, have heard of or know of AWESOME products on the market, etc... bring them up here. I would love to know of anything beneficial to the care of my reptiles, and of course any special methods or secrets. Talk to you soon!
