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.
The comfort zone for hermit crabs is 70 to 75 degrees Fahrenheit. That is when they are most active and healthy. If the temperature drops to between 50 and 60 degrees Fahrenheit, dormancy and hibernation will occur. A long hibernation may permanently affect the hermit crab.
