I'd place plenty of tight places for it to hide. Fake plants, hides, branches, etc. You don't have to limit yourself to two hides. As they get older, you'll remove them because the animal will require more room to move about. As hatchlings though, large enclosures can be overwhelming and stressful.
Another suggestion would be a plastic container while it's young and becoming acclimated. For a relatively low price you can give it several appropriate sized enclosures, and then as a sub-adult you can move it to the 30/40 Gallon.
It's wonderful that you are doing research so far ahead. I'm sure you'll get everything worked out!
