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 good range for humidity in a crabitat is 75-78%. If you are keeping Strawberry hermit crabs, the humidity should be higher (80%). The first step to creating and maintaining humidity in your tank, is a good lid. A screen lid alone is not sufficient. A glass/plexiglass/lexan lid, cut to fit is the best option.
