>>Hi all,
>>
>>im new to this forum as of today and i desperately need all of your help i live in maine, and im 19 years old. i recently bought 2 leopard geckos after gucci passed away. i have had them for about a week now and they came home healthy and eating. after a few days the crickets stopped dissapearing at night. they are in a 10 gallon tank with sand substrate and have plants and a half log ( im sure youve seen what im talking about) for sleeping and napping and of course water. i have the day light on till about 10pm and then i switch to the night time red bulb. the temp is 80-85 degrees. they are both beautiful! the female (has albino colors) was the first one that cought my eye. and the male is brilliant yellow with black and orange..and white on his tail. after about 4 days they stopped eating crickets and i went back to the pet store and asked what to do. they now get beef baby food 2 times a day. the males tail is still nice and plump and he is alret but the females tail has thinned out a lot and all she ever does is lie around. this morning when i went to pick her up, instead of her scurrying like the little male she just laid there and let me pick her up ad didnt even try to jump out of my hand like her normal ritual. i live in the basement (finnished) of my house and its moist down here. there is a dehumidifier running keeping it at 50% moisture. there is also a dish of baby meal worms at all times for them to munch on if thye should get hungry but they have not eaten a single one. can any of you see what im doing wrong or are there any other questions you need answers to to figure out whats wrong? please help!!!!!

Several things:
1) 10 gallons is fine for one leopard gecko, but for 2 I'd like to see more like 20 . They may just be stressed from being in too small of a space together. I'd either go to a bigger tank or (preferably) separate them. They do not need companionship, and can in fact be stressed by it. How old are they? If the male is old enough to want to breed, he might be harassing the female too much - breeders typically either keep them separate except for a few days at a time or keep 4 females with one male so that he keeps busy w/o driving any one female nuts.
2) Sand = bad. Whoever told you it was ok was wrong. It can cause very serious problems. Over the short time you've had the geckos, it probably hasn't caused the current issue, but you don't want to keep them on that long term regardless. It can cause impaction of their digestive system (frequently fatal), because they ingest it when eating crickets, and sometimes just eat it on its own. Paper towels, slate, or lead-free tile are the preferred substrates for leopard geckos. I prefer paper towels because it makes cage cleaning a snap. Pull out hides, pull out paper towels, put in new paper towels, put in hides, done.
3) Sometimes a half log or similar hide doesn't let them feel secure enough. Try giving them something that's completely enclosed and dark inside.
4) If the female doesn't react at all to you messing with her, she's probably either very stressed or quite sick. If it's at all possible, separate them from each other and try just leaving her alone for a few days, then offer food again (either crickets or mealworms). If she's not doing better within a few days of that feeding attempt, I'd look into finding a good reptile vet in your area.
5) Finally, it's typically bad to handle them in the morning/daytime if it can be avoided. They're nocturnal animals, so this is the equivalent of a giant taking the roof off of your bedroom and picking you up at 3 am. Would you like that? I didn't think so. 
Best of luck, hopefully this has helped.
