General Description
The Sea Urchin, scientifically known as Tripneustes ventricosus, belongs to the Echinoidea category and is commonly referred to as the Sea Egg. These creatures vary in size, with a maximum size of around 10.0cm, and are typically found in the Mexican Gulf in the West Atlantic region. They are known for their ability to maintain a balance in the aquarium ecosystem by feeding on various types of algae.
Aquarium Suitability and Demands
Sea Urchins like the Tripneustes ventricosus species are suitable for aquariums with proper care. They require a larger tank size of at least 400 liters and are considered peaceful in temperament. They are known to be average in hardiness and can be a valuable addition to an aquarium setup due to their algae-eating habits.
Care and Hardiness
Sea Urchins are generally hardy creatures, but they require specific water conditions to thrive in captivity. They prefer a pH level between 8.1-8.4, a temperature range of 22.2-25.6°C, a salinity level of 1.020-1.025, and a carbonate hardness (KH) of 8-12. It is essential to acclimatize them slowly to any changes in water parameters.
Reef Suitability
Sea Urchins like Tripneustes ventricosus are often considered reef-safe. However, it is crucial to note that they may rearrange rocks and corals while foraging for food, which could potentially disrupt coral structures in a reef tank.
Aquarium Setup
For optimal care, provide Sea Urchins with a spacious aquarium that includes sand and coralline algae for them to thrive. They require a diet consisting of macroalgae like seaweed or nori, as well as microalgae such as spirulina. It is essential to ensure that the tank has sufficient algae growth to sustain these creatures.
Behaviour
Sea Urchins are known to be peaceful in temperament but have a tendency to move rocks and shift corals in their search for food. They can inadvertently overturn corals that are not fully secured, so careful consideration should be given to the placement of delicate coral structures.
Feeding and Diet
Sea Urchins primarily feed on algae, making them effective algae eaters in aquarium settings. Providing them with a varied diet of macroalgae and microalgae will help meet their nutritional needs and ensure their well-being.
Habitat and Distribution
Found in the Mexican Gulf in the West Atlantic region, Sea Urchins like Tripneustes ventricosus typically inhabit areas with ample algae growth. Their natural habitat includes sandy substrates and coralline algae, which provide them with both food and shelter in the wild.
