Überblick

This Crustacean serves as a algae + detritus cleanup in the reef aquarium. Rated easy difficulty, it requires a minimum tank size of 10 gal (38 L). Reef safety varies by individual. Understanding where this invertebrate fits in your reef ecosystem helps you stock appropriately and avoid common compatibility issues. Unlike fish, invertebrates are generally more sensitive to water quality—particularly copper, which is lethal to most marine invertebrates even in trace amounts.

Beckenanforderungen

A minimum tank size of 10 gal (38 L) is recommended. Maintain pristine water quality with standard reef parameters:

Temperature: 75–80 °F (24–27 °C)
pH: 8.0–8.4
Salinity: 1.024–1.026 sg
Alkalinity: 8–11 dKH
Ammonia / Nitrite: 0 ppm
Nitrate: < 20 ppm

Critical: Never use copper-based medications in a tank containing invertebrates. Even trace copper from treated equipment can kill shrimp, snails, crabs, and other invertebrates. If you have used copper in a tank, it is absorbed into the silicone sealant and rocks, making the tank permanently unsafe for invertebrates.

Ernährung und Fütterung

This species is primarily an algae grazer that feeds on film algae, microalgae, and detritus growing on rockwork, glass, and sand. In a well-established tank with natural algae growth, supplemental feeding is usually unnecessary. In clean tanks with limited algae, supplement with blanched vegetables (zucchini, spinach) or sinking algae wafers. Do not rely solely on this species to control a major algae outbreak—address the root cause (nutrients, lighting) while using grazers as part of the solution.

Verhalten und Verträglichkeit

Reef safety varies. Research specific compatibility concerns for this species before adding to a mixed reef. Avoid housing with aggressive predators that may eat invertebrates, such as triggers, large wrasses, or pufferfish.

Acclimate all invertebrates slowly using the drip acclimation method over 45–60 minutes. Invertebrates are more sensitive to salinity and pH swings than fish, and sudden changes can be fatal. Never expose marine invertebrates to air or freshwater.

Häufige Fehler

Skipping drip acclimation. Invertebrates are far more sensitive to parameter differences than fish. A rushed acclimation is the number one cause of invertebrate loss.
Copper exposure. Any copper in the system—from medications, plumbing, or contaminated equipment—kills invertebrates. Test for copper before adding invertebrates to a new or medicated tank.
Overstocking the cleanup crew. More is not always better. Too many snails or hermits for the available algae leads to starvation. Stock conservatively: 1 snail per 2–3 gallons, 1 hermit per 5 gallons.
Ignoring predators. Many popular fish (wrasses, hawkfish, dottybacks) prey on small invertebrates. Research compatibility before combining.

Tipps für den Erfolg

Drip acclimate for at least 45 minutes before adding to your tank.
Never use copper-based medications in a tank with invertebrates.
Stock cleanup crew members conservatively—they need food to survive.
Provide empty shells for hermit crabs to prevent them from killing snails for their shells.
Monitor new additions for the first few days to catch compatibility problems early.

Häufig gestellte Fragen

How many should I add to my tank?

For cleanup crew members (snails, hermits), a general guideline is 1 snail per 2–3 gallons and 1 hermit crab per 5 gallons of tank volume. For specialty invertebrates (shrimp, crabs, starfish), keep according to species-specific recommendations. Overstocking leads to starvation and territorial conflict.

Is this invertebrate reef safe?

Reef safety depends on the individual. Most specimens are compatible with corals, but monitor behavior after introduction. Remove promptly if you observe coral nipping or food theft.

What kills marine invertebrates?

The most common causes of invertebrate death are: copper exposure (even trace amounts), poor acclimation (salinity/pH shock), predation by incompatible fish, starvation in overstocked cleanup crews, and exposure to air during transfer. Handle with care and maintain excellent water quality.
