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.
A hygrometer is used to observe the humidity inside the tank. Just as with temperature, humidity is very important. If the humidity drops and the air is dry, your land hermit crab will have difficulty in breathing through their modified gills. Humidity should be near 80% relative humidity.
