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.
What Affects Life Span. Habitat -- How you house hermit crabs will greatly affect how long they live. Hermit crabs do best in glass or acrylic aquariums decorated with branches, empty shells and plants. Keep the humidity between 70 percent and 80 percent, and maintain a habitat temperature of 75 to 85 degrees Fahrenheit.
