Suggested habitat

Leave a rubble zone and a few empty shells along the base of the reef; the sand surface and the crevices are its working area. Stable water matters more to survival than the layout.

Plates are husbandry references—not build plans or generator parameters. Check your own water, vessel, and stocking before you act.
