Isolation Units

Hermit Crab Paradise directory  Home » Hermit Crab Care » Isolation Units

Purpose

Isolation units are used to separate one hermit crab from the others. In shell fights, we recommend separating both the aggressor and victim each into isolation units to calm down and recover respectively. A surface moulter is very vulnerable to attacks and may have its shed exoskeleton stolen and eaten by other hermit crabs, so moving the moulter along with its shed exoskeleton to an isolation unit is a good idea if you do not want to set up a barrier around them. Isolation units can also be used to isolate new hermit crabs prior to introducing them to the old ones to help them relax as they move to a new home.

Set Up

Isolation units do not have to be made out of large aquariums; at most five gallons is sufficient, but it should be large enough so that you can fit in three small dishes and have room for the hermit crab to dig. Like any aquarium used to keep hermit crabs, it must have a glass lid to hold in the temperature and humidity to the crab-friendly range. Keep the isolation tank in a warm, dark area, preferably in a quiet place too.
If you have an unused, clean critter keeper, you can use it as an isolation unit by placing it inside the main aquarium (check out the photo below). The temperature and humidity for both can thus be monitored at the same time.
Bear in mind that an isolation unit should not be missing anything essential that the regular aquarium has. Every isolation unit should have small dishes for food, fresh and saline water, thermometer and a hygrometer. If there is room, add in a hidey hut or toy cave for hermit crabs who like to hide underneath one. The sand should be deep enough to cover the hermit crab fully plus an extra two inches or more if possible. The sand should contain the same level of moisture as the sand in the main aquarium; that is, just wet enough so that you can make a sand castle out of it. Also, mix some sea salt into the sand to hinder bacterial and mould growth.
