The smallest I have raised have been about 3/4 inch to 1 inch. But I have been doing some research on very small slings and a common theme is that they are particularly delicate at this stage. They apparently lack the protective skin of older tarantulas. So some extra care seems needed. Richard at Tarantula Collective says he keeps his small slings at somewhat warmer temperatures than his other tarantulas.Hopefully others will add more information and please definitely do more research if you want to try again.
