Overview
Pencil Urchin Black is a marine invertebrate suited for stable saltwater aquariums. Stable salinity, gentle acclimation, and compatible tankmates matter before it is added to a marine system.
Pencil Urchin Black is saltwater aquarium livestock suited for a stable, mature marine system with compatible tankmates, proper acclimation, and appropriate feeding.
Common Name: Pencil Urchin Black
Scientific Name: Heterocentrus sp
Care Notes: Review salinity, tank maturity, reef compatibility, diet, and tankmate requirements before ordering. Marine livestock should be acclimated carefully and added to stable systems.
Shipping & Arrival: Most in-stock livestock generally ships in 1–2 business days when weather, livestock condition, and carrier timing are safe. Open the package promptly, keep lights low, and acclimate before release.
- Tank maturity: Best in established marine systems with stable salinity and temperature.
- Temperature: Keep the aquarium in a stable marine range with minimal daily swing.
- pH: Stable marine pH matters more than frequent correction.
- Salinity: Match salinity carefully before acclimation.
- Diet: Keep species-appropriate foods ready before arrival.
- Compatibility: Avoid predators or tankmates that will harass shrimp, snails, crabs, or other invertebrates.
- Reef-safe notes: Review coral, anemone, clam, or cleanup-crew compatibility where relevant.
- Acclimation: Slow acclimation is important for many marine inverts.
- Shipping notes: Marine invertebrates are packed with stable-system arrival in mind.
