Black Long Spine Sea Urchin Diadema AntillarumThe Black Long Spine Sea Urchin, scientifically known as Diadema Antillarum, is a striking marine invertebrate found in the Caribbean Sea and the western Atlantic Ocean. This urchin is characterized by its distinctive long, black spines that can reach up to 30 cm in length, making it a visually captivating addition to any marine aquarium.The Black Long Spine Sea Urchin is an omnivorous species, feeding on a variety of algae, detritus, and small invertebrates. It plays a crucial role in maintaining the balance of coral reef ecosystems by controlling the growth of algae.When it comes to tank mates, the Black Long Spine Sea Urchin is generally peaceful and can be kept with a variety of other reef-safe fish and invertebrates, such as clownfish, gobies, and shrimp. However, caution should be exercised as its long spines can pose a risk to more delicate tank inhabitants.Regarding its aggression level, the Black Long Spine Sea Urchin is considered relatively docile, but it may become more defensive if it feels threatened or its territory is encroached upon. It is essential to provide ample space and hiding spots in the aquarium to minimize potential conflicts.For optimal care, the Black Long Spine Sea Urchin requires a well-established marine aquarium with stable water parameters. The recommended water temperature should be between 72-82ยฐF (22-28ยฐC), with a pH range of 8.1-8.4 and a specific gravity of 1.023-1.025. Regular water changes and efficient filtration are crucial to maintain the necessary water quality.Overall, the Black Long Spine Sea Urchin is a captivating and unique addition to a marine aquarium, but it requires experienced aquarists who can provide the appropriate environment and care to ensure its long-term health and well-being.

You can wear them in the water because they are 14 k gold
Love these earrings. They were a little smaller than I thought and the clasp gets wonky after a while.

These have been a conversational piece
Style: 16mm Rose Gold
I thought these were cute. I purchased two sets because I have two holes. They seem like a good quality of rose gold. They are not to big but the heart just hugs my ears.
