anyway, she already has a 10 gallon tank, but should she get a 20 gallon instead?
A ten gallon tank is the absolute minimum for 1 leo. But, as with most animals, bigger is better. When I got Cleo, what I lacked in was space, so she's in a ten gallon.
so, do you think we should get a 20 gallon? if so, long, breeder, or regular?
If you decide on getting the 20g, go for the long. Leos are terrestrial so need more floorspace thant space up. I don't really know how much floorspace a breeder tank has, but if it has more floorspace than the long, then go for that.
do we need uvb lamps?
Leos are nocturnal, so they don't need UV lamps
should we have a undertank heater and a incandescent bulb? or is just a light enough to provide heat? if so, what wattage?
Leos are from the desert, so they need a pretty warm, dry tank. You need to have a temperature gradient, one side of the tank should be around 85-95 (the warm side) and the other side should be at 70-77 (degrees F) during the day and at night it should be at around 68-74 degrees. To achieve this temps. you'll probably need a UTH and a heat bulb (normal bulb will do). check the temp with the UTH and regulate the heat you need with the bulb. To regulate it you should test with bulbs of different watts and at different distances from the tank. You need a termometer in each side of the tank for it.
and how exactly to you "gutload" the live food? what kind of stuff do you feed them? do petstores sell live food that is already gutloaded?
Petstores usually don't feed them gut-loaded. There is a "cricket dust" that is supposed to be complete nutrition for the crickets. Remember that you need healthy crickets to have a healthy leo. I don't really know if the dust is really any good for it, and since it can't be found in any pet store here, I just don't use it. Crickets are ovnivores, and they eat everything that's edible (and some things that are not edible too..) I feed them a variety of things. Potato, carrot, hamster/gerbil food, mice/rat food, fish food, apple (and apple cores), dog food, rolled oats... I'm supposed to feed it dark greens, but I can figure out what are the things that they suggest me to (LOL). Be creative...
if we use a 20 gallon, would it be better to have more than one gecko? are geckos sociable(as in do they like companions, not will they get along with humans)?
Leos are not exactly social creatures, you can have one alone and it's perfectly fine. It's up to you if you want (and have the money to get) 2 of them. Now, there are a few rules if you want 2. THey have to be both females. 2 males would fight to the death and 1 male 1 female would be dangerous for the female, cause leos are harem breeders and the male would stress the female too much by trying to breed with her constantly. The other rule is that both have to be of the same size. If one is bigger than the other, it will bully the smaller around and can end up in the bigger on eating the smaller one
which do you prefer, male or female?
I don't really have the experience to decide if I like males or females better, since Cleo is my first leo. Now, you will most likely find females around (or at least temperature bred for females) since they can be kept in groups.
is sand ok as a substrate? one site i read recommended repterra, but i can't find it anywhere, and i really like the look of sand. i also read at a different site that only juveniles can't be housed on sand. is this true? should we just not take chances? we really want to avoid vet visits as much as possible, unless you have to take them for checkups(do you?). is reptibark ok?
Most of what I've read about sand is negative. Calci-sand is a big NO-NO.. don't even think about it!! Now, about playsand, I've read combined stuff. One thing everybody seems to say is that Juvies can't be housed in sand cause of the high risk of impactation. Some websites say that sand is OK for an adult. Impactation is the blockage of the digestive tract. The thing is that there are 2 types of impactition; chronic and acute. Acute impactation is when the reptile swallows large quantities of sand and gets completely blocked. It can cause the death. Chronic impactation is when the leo swallows sand (or any granular substrate) slowly through a long period of time. Usually goes unnoticed and the life of the reptile is cut short cause of it.. and when found it's usually too late. Now, the problem is that leos like to lick the substrate, so they usually eat a bit of it whenever they do it. Honestly, I didn't took the chance and have been using paper towels and tiles as substrate, just to be on the safe side.
can leo's bite? do they even have teeth, or just sharp jaws like turtles?
I'm not really sure if they have teeth or not.. they bite, but from what I've heard, they don't bite hard. Cleo hasn't bit me yet, she did hissed/snapped a me whenever I spray her moist hide with her inside (hehehe). They are pretty easy going when you hold it. Cleo likes to climb to my shoulders or get on top of the puter (laptop) when I take her out. I think they are one of the most easy going reptiles out there.
Here is a pic of my enclosure:
It has changed a bit till I took the pic, but I don't want to take another one till I get it finished. 8)
