Steinitz Goby

The Steinitz Goby (Amblyeleotris steinitzi) is recognizable by a pale body crossed by reddish-brown bars. Color and pattern may vary with age and individual condition. Allow room for a full-sized shrimp goby at the burrow entrance and use broad cover at the base of the rockwork.

Its natural range is Indo-West Pacific. It is associated with sand and rubble near coastal reefs. It spends much of its time near shelter and makes short excursions to feed.

In the aquarium, give the Steinitz Goby a mature system with its own feeding area and a retreat suited to its behavior. Plan space for the adult and check that faster fish cannot take all the food before it reaches the intended area. Prepare the permanent aquarium around its adult requirements even if the fish arrives small.

Tank Requirements

Use at least 30 gallons for long-term adult housing. The species reaches 5.1 inches (13 cm standard length) based on published measurements. Standard length excludes the tail fin. Leave additional space around the fish’s retreat to accommodate its full length.

Build a sheltered sand-and-rubble patch against stable rockwork. Use enough fine sand to support a burrow and scatter a few small shell or rubble pieces a shrimp can move. Leave a clear view and a small open feeding area immediately outside the entrance.

A compatible pistol shrimp can excavate while the goby watches for danger. Introduce partners where both can find cover, and give them time to settle. A shrimp partner is optional unless the listing explicitly includes one.

Maintain a secure cover and stable rockwork. Close gaps at cable runs and plumbing. Check that rock is firmly supported, particularly where a burrow or shifting sand could undermine a piece. Leave a clear path around the shelter for feeding and routine maintenance.

Use an established biological filter with steady circulation and surface agitation. Set up the main retreat before introducing the fish so it can find cover promptly. Balance circulation with a sheltered area where the fish can rest without continually swimming.

Observe how the fish uses the layout after introduction. The first shelter it selects may differ from the one you planned. Shift the feeding location to its actual retreat, and make sure there is another route to cover if a tankmate begins using the same area.

Diet and Feeding

The Steinitz Goby is a carnivore that takes small animal foods. Release food in the current near the burrow or use a feeding tool to place it just outside. The fish should be able to make a short feeding strike and return to shelter.

Rotate suitable foods from these options.

• Appropriately sized mysis or enriched brine shrimp
• Finely chopped marine shrimp or other marine seafood
• Balanced frozen marine carnivore preparations
• Small sinking marine pellets once accepted

Offer one or two small meals per day as a starting point. Adjust portions to the fish’s size and what it takes during each meal. Start with a few small particles near its shelter before feeding the rest of the aquarium.

Verify that the fish swallows the food. An approach or a feeding strike does not establish how much it ate. Observe several meals, especially when a new fish stays under cover. A reluctant new arrival may respond first to small frozen or enriched live foods. Introduce complete preparations as feeding becomes consistent.

Watch for a pinched belly, repeated spitting, or a change in the fish’s usual feeding position. Try smaller particles or a second delivery point before increasing the total amount offered. Remove leftovers that collect under ledges or settle where the fish rarely feeds.

Temperament and Tankmates

Peaceful fish that feed higher in the aquarium are good candidates. The goby can defend its burrow entrance, especially from other shrimp gobies. Provide a separate sand patch for each compatible pair.

The Steinitz Goby is generally peaceful toward unrelated fish. Most stocking problems appear when another fish can occupy the only retreat or reach every feeding location first. Give tankmates an alternate route and use rockwork to interrupt sight lines.

Signs of a poor match include sustained chasing, fins held close to the body, and a fish that repeatedly misses meals or stays out of view during its usual active period. Offer food near an alternate shelter and monitor whether the fish resumes feeding. Use a divider or separate suitable housing if it continues to lose access to food or cover.

Reef Compatibility

The Steinitz Goby is Reef Safe with corals and typical reef invertebrates. Provide enough space for its feeding route and shelter as coral colonies grow.

Deliver portions the fish can take without allowing uneaten food to collect in the rockwork. In a mixed reef, keep feeding access open as colonies grow and maintain circulation around sheltered areas.

Water Parameters

Temperature: 75–78°F
Specific Gravity: 1.024–1.026
pH: 8.1–8.4
Alkalinity: 8–12 dKH

Use a fully cycled aquarium and keep ammonia and nitrite undetectable. Maintain steady specific gravity through top-off and match replacement saltwater during water changes. Check temperature and flow after maintenance or changes to the equipment.

Watch how feeding affects nutrient levels over several days. Clean mechanical filtration before trapped food decomposes and siphon accessible debris. Keep oxygenation steady overnight and during warm weather.

Establish a baseline for the fish’s activity, feeding response, and use of its retreat. A quiet or cryptic fish may still be feeding normally when approached at the right time of day. A marked change from that routine warrants a check of water quality, temperature, and tankmate behavior.

Common Considerations

• Adult Housing: Provide 30 gallons or more for adult housing. Up to 5.1 inches (13 cm, standard length).
• Species Notes: Allow room for a full-sized shrimp goby at the burrow entrance and use broad cover at the base of the rockwork.
• Feeding: Start with one or two small meals per day. Confirm how much the fish swallows and track body condition.
• Shelter and Equipment: Provide suitable cover, secure the lid, and keep intakes safe for the fish’s size.
• Tankmate Selection: Choose fish that leave access to food and a retreat. Check for repeated chasing or missed meals.
• Reef Compatibility: Compatible with typical reef livestock. Keep feeding areas and shelters accessible as the aquarium matures.
