While not fully aquatic these guys are really cool and easy to care for. They require an area where they can climb out of the water, although here they spend most of their time submerged. They’ve quickly become one of our favorite residents and have a 10 Gallon tank to themselves!
these guys have a couple particular care requirements, but are incredibly easy to care for and are one of the hardiest invertebrates we have seen. They require brackish water and we use reef crystals from Amazon. We mix tap water half the specified levels on the box (to achieve 1.012 salinity). Being exact is not critical at all here! They will thrive in a very wide range of salinity levels in nature. This value is in the dead center of this range. They seem to really love Hikari Crab Cuisine!
