Archaster typicus – Detritivore Sand Starfish

Archaster typicus is a gray starfish renowned for its efficiency in maintaining the sand in reef aquariums. This very discreet species spends most of its time buried in the substrate, where it actively participates in the elimination of organic waste.

A natural detritivore for the sand bed

Thanks to its burrowing behavior, Archaster typicus regularly stirs the top layers of sand, thereby preventing the accumulation of sediments and the development of anaerobic zones. It is therefore very useful for maintaining a healthy and oxygenated substrate in your marine tank.

Its flat, star-shaped gray body allows it to blend into the substrate, making it a barely visible but indispensable species. It is an excellent choice for aquarists seeking a deep clean of the sand.

Maintenance conditions

• Minimum recommended volume: 150 liters
• Temperature: 24°C to 28°C
• pH: 8.0 to 8.4
• Substrate: minimum 3 cm layer of sand, medium to fine grain
• Compatibility: excellent with fish, corals, and invertebrates

Behavior and utility

This starfish is peaceful and 100% reef-safe. It does not attack corals or other invertebrates. Its action is targeted on the upper layer of the sand: it does not clean deeply below 3 cm.

Its detritivore activity focuses on waste, micro-algae, and small organic particles, which it filters while slowly moving under the sand.

Why choose Archaster typicus?

• Natural cleaning of sand in marine aquariums
• Peaceful and discreet species
• Maintenance of the superficial layer of the substrate
• Prevents the accumulation of waste and dead zones
• Ideal for reef aquariums from 150 liters

Invisible but valuable, Archaster typicus is a valuable ally for keeping sand clean, oxygenated, and alive in your reef aquarium. It acts efficiently and discreetly to maintain the biological balance of the substrate.
