Yeah but you shouldnt house a 25 gram gecko with a 50 gram gecko. They may appear friendly but they can turn against eachother at any time. Reptiles dont make friends, its all about territory, not dying and food for them.
Honestly, I wouldn't. I do know people that do though. If you end up deciding to go ahead with it, you'll need to watch them closely for bullying during feeding. It does not matter how "friendly" they are toward each other when it comes to that. They all sound fairly young (due to their weight) and young'ns are little horses...if they don't get the right nutrition at that age it would stunt their growth I fear.
My sweetest female in the world turns into the Incredible Hulk when it comes to feeding, and will not let ANYTHING near her food...male, female, me lol.
