Hi, i am just getting some about 3 week old crested geckos. I'm going to get 3. The tank i have is L30xW12xH22. My question is, is the tank to big? Will it be too big for them to hunt down the crickets? Also, the normal temp in the tank is 60F. So, i'm going to use a 40watt light bulb. Is that a good idea? Thx, for any help.

That tank is fine for a couple adults, way too big for 3 week old babies. I kept my baby crested geckos when I was breeding, in small dry storage containers I bought at the dollar store. These were about 12"x8"x4". I kept babies in these individually for several months (usually till I sold them at 3-4 months of age). These small containers are good till the gecko is 4-5" long (maybe a bit less, hard to remember now as its been a few years since I bred them and don't have any of the old containers lying around).

To be honest, buying 3 week old crested geckos isn't a good idea..at this age they are still very fragile. I would wait till they are at least 4 months old before buying. This way they are well established and have some size to them. (Unless you meant they are 3-4 months old to begin with and that was a typo in your post).

Also, since 3 weeks (or 3 months for that matter) crested geckos are very difficult to sex, even when comparing pore rows, as often they haven't developed fully at 3 weeks. Thus, it would be best to house them all separately till they are at least 9 months old. This ensures any males who are late bloomers can be accurately sexed. You don't want to have a couple of males together.
