General Description:
The Banded sea urchin, scientifically known as Echinothrix calamaris, belongs to the Echinoidea family. These sea urchins are known for their effectiveness in controlling algae growth within aquariums. They can consume various types of algae, such as coralline algae and green hair algae, making them valuable additions to marine tanks.
Aquarium Suitability:
The Banded sea urchin is considered suitable for most aquarium setups, given its peaceful temperament and effectiveness in algae control. However, due to their sensitivity to changes in salinity, they require slow acclimatization when introduced to a new tank. This species is nocturnal, being most active when lights are dimmed or turned off.
Demands:
This species has average hardiness and will thrive in aquariums with stable water conditions, with recommended parameters including a pH of 8.1-8.4, a temperature range of 22.2-25.6°C, and a specific gravity of 1.020-1.025. They prefer a carbonate hardness (KH) of 8-12.
Care and Hardiness:
The Banded sea urchin is relatively hardy and can adapt well to various aquarium conditions as long as water parameters are maintained within suitable ranges. Adequate hiding places, such as crevices between live rocks, should be provided to ensure their well-being.
Reef Suitability:
Banded sea urchins are reef safe and can be kept in reef aquariums without posing a threat to corals or other invertebrates. They primarily focus on consuming algae, making them beneficial additions to the reef ecosystem.
Aquarium Setup:
A minimum tank size of 400 liters is recommended for keeping Banded sea urchins. The aquarium should provide ample live rocks with hiding spots for the urchins to retreat to during the day. It is crucial to ensure a well-established algae population to sustain them over time.
Behaviour:
These sea urchins exhibit peaceful behavior and are generally unobtrusive in the aquarium. Their nocturnal nature means they will be most active during the night or when the tank lights are off.
Feeding and Diet:
Banded sea urchins are effective algae eaters, consuming macroalgae like seaweed or nori, as well as microalgae such as spirulina. While they can help control algae in the tank, it is essential to monitor their diet to ensure they receive sufficient nutrition.
Habitat and Distribution:
The Banded sea urchin is found in various regions, including the East and West Indian Oceans, Australia, the Red Sea, Indonesia, and the Central/West Pacific. They inhabit rocky reefs and coastal areas where they play a vital role in maintaining the ecological balance through algae consumption.
