Hi, I recently bought 2 baby leopard geckos at petco because they were on sale(2 for the price of one!) and i was wondering.. how do i tame them or get them to like me? one of them lets me hold him/her but the other one bit me hard! what do i do?
p.s. since it bit me(last week) i haven't held any of them.

Answer
Wow, that's a horrible sale...you really will need a second enclosure.  Adult leopard geckos can be housed in pairs or trios, but males can never be housed with other males, and males and females shouldn't be housed together until they are of a proper weight for breeding, once they are juveniles.  They will breed too early, which can be very damaging to the female's health.  There's no practical way to sex them when they are babies, so keeping them separate is the surest way to prevent aggression, and keep them healthy, until you are certain of their genders.  They might be able to be kept together for a few months, if they are of a very similar size and both are very healthy, but you will have to watch them carefully to make sure one baby does not dominate and stress out the other.  If one baby eats less, separate them promptly.  

First, leave them alone for a couple of weeks, to get used to their new surroundings, and make sure both are healthy and are eating well.
Then, you can try scooping them up carefully and getting them used to handling.  Keep handling sessions short, perhaps 15 minutes per day, per animal, and back off if their appetite decreases.  Do not grab them to pick them up, and try to approach from the side, and not from above.  Move slowly, but without hesitation.  They are babies, of course, so they believe that everything is a predator out to eat them, and naturally they will defend themselves in any way they can.  Reptiles are not the brightest creatures, so it will take time for them to learn that you aren't a threat.

The littlest ones may stand up tall, open their mouth wide, and even scream at you, as well as biting.  Try to give them as little time as possible to practice this type of behavior, because behaviors that they repeat often will become habits hard to break in the future.  It's sometimes better to leave them alone, than to attempt handling when they are in that mood.

To pick them up, approach slowly, and scoop them up from the side, rather than from the front.  Let them walk from hand to hand without restraining them (this will require patience).  You can also work with them by offering food from tweezers, and by simply putting your hand in the cage without touching them, if they are particularly skittish.  Patience is the key.  As they grow larger and older, they will become less high-strung, and less skittish and defensive, so working with them will become easier.  Expect to need several months of daily work to tame them completely, and remember that they are reptiles--they will never seek affection, and don't particularly enjoy being handled, but they can become very used to it.

Fortunately, even a hard bite from a baby leopard gecko is no big deal.  (A bite from an adult does hurt a bit--they have strong jaws--but a tame adult is extremely unlikely to ever bite, unless unexpectedly grabbed and scared).

Baby leopard geckos grow FAST--make sure their temperatures are correct, and they get as many calcium dusted crickets, and other insects (such as phoenix worms), as they can eat, once a day, until they are grown (at that point, they eat every other day).  You can put the insects in one at a time, and continue until they stop accepting them.  Remove any that remain in the enclosure after 15 minutes, so they will not nibble on your lizards.  Remember that all feeder insects you offer should be no larger than the space between the lizard's eyes (and don't let the pet store convince you to offer crickets that are larger than this, as they may damage the baby's jaws).
