Python,
Congrats on your new additions -- leos are great [img]modules/Forum/images/smiles/icon_smile.gif[/img]
First of all, you might want to take them into a vet and have them checked out, and tested for parasites etc -- one problem with buying herps from a pet store (especially chain ones like PetCo) is that they often come along with extra little "goodies" that you weren't really counting on. My first leo, Path, I got from a pet store, and she must have had something when I got her because she started wasting away within a little while of getting her. I think that Pet Co has some kind of guarantee on their animals, right? So if there's anything wrong with them, you might be able to get them to pay for the bill, or something...
Second... baby leos should be fed every day, around 5-6 appropriately sized crickets -- they're probably almost big enough to start feeding them 1/2" crickets. If you like, you can also leave a dish with a few small mealies in it in their tank, and they can snack on those whenever they get the munchies. You should be dusting their food with calcium/vitamin powder at every feeding for now, and also have a dish of calcium available in their tank. It's up to you whether to leave water in there at all times, or to put it in there only 3-4 days of the week. They don't really NEED it there all the time, but personally I keep it there, just in case.
Temp should be at around 80-85 on the warm side... they'll need a humid hide on the warm side to help them during shedding (which the little guys do a lot more often than the adults), as well as a dry hide... and then a dry hide on the cooler side as well.
Best to keep them on paper towel while they're this young, the risks of impaction if they're on sand would be too great. Once they've grown to at least 6", you can switch to sand if you like.
You probably won't have much luck sexing them at this age -- but, being from a petstore, there's a good chance that they were incubated to be females, and thus probably ARE females. 3 full grown leos in a 20 is ok -- 4 might be pushing it. Just keep in mind that if more than one somehow turns out to be male, you'll have to move one of them out of there, or they'll hurt each other. Once they're around 4-5 months old you'll be able to sex them a bit better. At 6 months, the hemipenal bulges on the males start to become more obvious -- you can also look for the preanal pores, which will be in a chevron shape just above the tail.
If you go here:

HTH a little, feel free to ask any more questions that you might have!
