I went to my 1st reptile show today (yay) we got another leo for my bro and a fat tailed geko for me and we thought we could put the two Leopard Geckos together (that's what the dude said) but he was wronge when we put them in together mine (bigger one) started waveing it's tail and staring at it my bro's ll dude is small and couiros and didn't move and we didn't like so we took my brother's out.What was she doing to the smaller one?Was it ok and put them back together? I have the other in a ten gallon right next to the other shareing the uv light but he/she can't stay in there for long. What should we do?

Hello,
Leopard Geckos don't require any UV light at all. The tail twitch was a male displaying that he was a male. If the other gecko twitched back, they would have fought. If left together, they will eventually fight.
Those 2 geckos need to be housed separately. They are different species.

1st) there's two kind of uv's uva (heat) uvb (sunlight)
2nd) I have a female leo (unless the person who typed the caresheet up made a typo)
3rd)it really wasn't a "twitch" it was more like a wave
maybe that'll help answer the question

ok I just "re-interdouced" them to eachother and the bigger one just licked the little one so is ok now?

hi mike,

may I have a shot at this?

1. technically, leopard geckos don't really need any light at all, outside of the natural light of a bright room. they are nocturnal, so they don't "bask" like bearded dragons and chameleons and such diurnal reptiles that require uv light. mostly the lights that people put on their Leopard Geckos is for heat, plus it is important to provide a cycle of day and night for breeding purposes. you could use a regular household lightbulb or any generic halogen bulb and as long as it produces the right amount of heat you would be all set.

i keep lights on most of mine, mostly for breeding purposes, a lot for display reasons. the ones I don't have lights on are in a pretty bright room and so i'm not too concerned about them not knowing when to sleep and when to be awake and eating. in the height of summer when it's really hot here, i turn off most of their lights during the day. does any of this make sense? i can be pretty confusing sometimes...

2. you can definitely tell a male from a female when they are big enough. you will see two "bumps" between the base of the tail and the vent. if these are not there, then you have a female.

3. well, this really isn't a reply to your number 3 above, but more so for the original question. how old/big is your leopard gecko? how old/big is your brothers leopard gecko, the new one? how much difference is there between them?

if the bigger one is adult and the small one is just a tiny baby, the adult will kill and eat (or attempt to) the baby. if the bigger one is a bit bigger, then there is a decent chance that the big one will act dominating, and may bite and fight the smaller one, also may intimidate her so that she refuses to eat.

if there is only a very small difference between sizes, they may get along just fine. however, there is always the chance that the original leo will be territorial and try to protect her home, causing fighting. to remedy this, you would have to clean and disinfect everything in that cage, and put both geckos in at the same time so that not one of their smells is in there first.

geez, hope I helped! good luck and I hope they are getting along,

Actually, UVA isn't heat, Its also found in sunlight, just like UVB. The reason some reptiles need UVA is because some can see into that spectrum. Without it, things don't look the way they should and the reptile gets stressed. Iguanas and anoles are some of the reptiles that can see into the UVA spectrum. If you have a UVB light, it automatically aslo gives off UVA. However, you may notice that UVB lights don't give off much heat (unless its MV). If you have a UVB light and you buy a UVA basking light then you're wasting your money cause you already have the UVA in the UVB light. As long as there's a UVB light prsent a normal household lightbulb will work as the heat light. lol, sorry, this really doesn't have much to do with your problem. Just thought I'd clarify some info though.

oh, and one other thing, mike. i don't mean to nag, , but it's generally best to quarantine new animals for a while before introducing them to your original ones. there is always a chance with any new critters that you bring into your house that they will be carrying parasites or mites, and if so, they will infect your original lizards, too.

but, i have also gotten impatient and excited for new to meet old, and put them together immediately, and I have been very very lucky...

Nicely said Lola, but I feel I should add to some thing here. If either one of your geckos bit one another you should not reaqaint them at all. You can and probably should quarantine the new gecko for at least 60 days. Just to be safe. Making tank accessories and needs are not hard at all. You can achieve this by using pure tubbaware products, knife to cut, and a lighter to smooth edges.

For your other post: Leopard Geckos are nocturnal and don't require any uv at all. A under tank heater is a perfect source of heat. 2: If they are both female, male, or both different sexes they still can be VERY territorial. I highly reccomend you remove them again as it can happen again. It can happen on and off. Even when you can't see it. If the one decides to bite it could lead to death. The stress caused in the tank can cause both of them to not eat and get sick. 3:Twitch or wave it was a sign of aggressiveness. quite smaller Leopard Geckos being housed with larger Leopard Geckos is risking the smaller leo's life. Reason is because the larger more in charge leo will mistake the small leo for food some times.

This is not to attack you. I am clearly trying to tell you information. Which some is already stated. So please keep them away from each other/ At least for quarantine.
