I do.
I had three in a twenty with three hides.
It was fine, but they were all sub adults. I couldn't imagine adults they are too big.
Two adults in a 20 is what I do,
One adult male in a 20.
I house most of my geckos together in groups with up to 3-4 in a 20 long with a heated12"x12" level. My geckos for the most part are pretty mellow and seem to stake out their own spaces and not bother each other. My AFT pair is also housed together full time and even though there are 3 hides, they seem to prefer to hang out together most of the time.
We have several 20 L with 2 in each and we have 4 females housed together in a 55. They all have their own hides and seem to get along fine. They are all big and healthy.
I found that 1.2 leos in a 20L was adequate, but occasionally they would compete for the best hangout/hiding spots. Now, with 2 leos per 20L, they seem more relaxed. I think personalities are a huge factor.
i have 4 juvies in a 50 gal. (12"x48") with 7 hides. i started with only 4 or 5 hides and expanded when new ones came available to me.
two almost always stay together in the hide on top of the humid hide. meanwhile the two piggies don't like to get too far from the mealie dish.
they had some issues in the very beginning accidentally nipping each others' tails at feeding time, but no tail losses.
the tank is 18" high, so i need to build a second level when i can get some free time. i'm trying to draw up some plans right now. they're getting a little bit big for their hides and i really want to be able to get some more hides and another feeding dish or two in there before long, the dimensions are just so not ideal for terrestrial geckos.
I have 2 50 gallon tanks. The demensions are 18x36x18. I house 3 females in each tank. Most of the time everything is ok. I have had one female that is really agressive to other females. When i started housing her by herself everything turned out fine.
i housed 3 in a 30 tank but have only just tday seperated them my largest and oldest sky has bi put in a seperate 10g tank os she dosent seem to b eating so i hsve jst put her in quarentine to keep an eye on her
I recently bought 2 two year old female geckos from a guy and he said they have been together since they were babies so I didnt want to separate them. They seem to actually enjoy each others company. I have them in a visionarium together. 30x12x12.
I tried housing together but always had issues with bullying. I housed 2 babies together since the beginning of october and at first everything was okay. Then I noticed one of the babies hiding himself in the weirdest of places where it could barely fit. When I watched them one day when I was feeding them, the baby came out from hiding to get a cricket only to be chased back where he was by the other one. So I separated them. I'm going to wait until their old enough that I know their genders (I have 4 total) before I start trying to house anyone together again.
I have 1.5 in a 50gal setup. I have multiple hides, readily available water, heat, and food. No problems here. In fact, despite numerous similarly prepped hides, they seem to congregate.
