onestly Repashy is the way to go. I tried clarks once on my picky eaters, none of them eate it, and even my non picky eaters didnt eat it, I only had a couple out of 20+ eat it. If you have a picky eater have you tried the part 2 diets? I find Mango and Passionfruit is a big hit here. Also some reluctant eaters will eat CGD when mixed with from fruit puree. I had found when I bought an adult female garg from someone, who fed baby food and clarks and the occasional CGD, she woulnt eat plain old CGD. I mixed mango puree (Looza or Hero brand from the grocery store will work) with water (50/50 or a 60/40 ratio) then mixed that with CGD as usual, and she ate it up. I then bought the mango part 2 which she happily ate. She now readily eats the normal CGD.
Although Clarks isnt a terrible food IMO it isnt as complete as Repashy, it would make a good treat but I personally wouldnt offer it as a main diet. Here are a few threads going on pangea about the product and what people there think of it.
