Blood loss [edit]. Hemorrhaging is broken down into four classes by the American College of Surgeons' advanced trauma life support (ATLS). 1  Class I Hemorrhage involves up to 15% of blood volume. 2  Class II Hemorrhage involves 15-30% of total blood volume. 3  Class III Hemorrhage involves loss of 30-40% of circulating blood volume. 4  Class IV Hemorrhage.
Each day, increase the thermostat setting by 2Â°C (3Â°F or 4Â°F) until you reach 28Â°C (82Â°F). If the newly adopted hermit crabs came from a tank that was already at 28Â°C (82Â°F), then keep the warm end of your tank at 28Â°C (82Â°F) from the first day. Pay attention to the temperature of the cool end.
Steps. 1  1. Provide your crabs with a glass tank. 2  2. Install the substrate. 3  3. Install a humidity gauge and two thermometers, One for the cool end, one for the warmer end.  4. Give your crabs hiding places and plenty to climb 1  on. 5. Place a fresh water dish and a marine salt water dish in the bowl. Some casual studies have found that Hermit crab salt water does not have any salinity to it, and lacks vital nutrients that are present in ocean salt water that the hermit crabs need. Provide your crabs with a dish of marine salt water.
