A community-rearing tank isn’t recommended. I’d set up a rack system for your hatchlings if you’re planning on breeding, and either separate each individual gecko into their own cage, or have geckos in a cage with their clutch mate. I’d recommended either 6-qt shoeboxes, or vision hatchlings tubs.
A community-rearing tank isn’t recommended because of the different hatch times of each clutch, you could have geckos that are 10-15 grams, and be putting 3-4 gram hatchlings in with them.
If you are unable to purchase or built a rack I wouldn’t breed.
