Sand Dollar Spiny Sea Urchin Echinoidea
The Sand Dollar Spiny Sea Urchin (Echinoidea) is a unique and fascinating marine invertebrate. Originating from tropical and subtropical ocean regions, this urchin has a flattened, disk-like body covered in short, dense spines that give it a distinctive appearance. Unlike many other sea urchins, the Sand Dollar Spiny Urchin has very small spines that are not sharp or venomous, making it a relatively docile species. It is an herbivore, feeding primarily on algae and detritus that it collects with its tube feet. This urchin is generally peaceful and can be kept with a variety of other reef-safe invertebrates and small, non-aggressive fish. However, it may compete for food and space, so appropriate tank mates should be selected carefully.Keeping a Sand Dollar Spiny Urchin requires an intermediate level of aquarium experience. It needs a well-established marine aquarium with stable water parameters, including a pH of 8.1-8.4, temperature of 72-82°F, and specific gravity of 1.023-1.025. Regular water changes and a strong protein skimmer are also essential for its long-term health and well-being.Overall, the Sand Dollar Spiny Sea Urchin is a unique and visually appealing addition to a marine aquarium, but its care requirements should be thoroughly researched and understood before attempting to keep one.
