Physical Characteristics and Identification
Identifying the Four Star Spear Gobby is relatively straightforward due to its distinctive physical attributes. These gobies are small, typically reaching a maximum length of about 2.5 to 3 inches (6 to 7.5 centimeters). Their body shape is elongated and cylindrical, characteristic of many goby species adapted for life on the substrate. The base coloration is generally white or pale, providing a stark backdrop for their striking markings. The most notable feature is the presence of four prominent black spots, or “stars,” along their dorsal surface. These spots are often ringed with a bright blue or iridescent hue, adding to their visual appeal. These spots serve as a camouflage mechanism, helping them blend into the sandy and rubble-strewn environments they inhabit in the wild. In addition to the black spots, Four Star Spear Gobies exhibit fine black lines and speckles across their body, further enhancing their camouflage. Their eyes are relatively large and positioned high on their head, providing a wide field of vision, which is essential for spotting both prey and potential predators.
The fins of the Four Star Spear Gobby are transparent with faint markings that complement their body patterns. The dorsal fin is divided into two parts: a spiny anterior portion and a softer posterior section. The pectoral fins are large and fan-shaped, which they use for maneuvering and perching on rocks or other surfaces. The pelvic fins are fused, forming a suction cup-like structure that allows them to adhere to the substrate, providing stability in turbulent waters. This adaptation is particularly useful in their natural reef habitat where wave action and currents can be strong. Distinguishing between male and female Four Star Spear Gobies can be challenging, especially when they are young. However, mature males often exhibit more vibrant colors and may have slightly elongated dorsal fin filaments. These subtle differences become more apparent as the fish reach adulthood, but careful observation is required to accurately determine their sex.
Natural Habitat and Behavior
Understanding the natural habitat and behavior of the Four Star Spear Gobby is essential for replicating their ideal environment in an aquarium. These gobies are native to the warm, tropical waters of the Indo-Pacific region, including areas such as Indonesia, the Philippines, and northern Australia. They typically inhabit shallow lagoons and coastal reefs, where they can be found among sandy substrates and rubble-strewn areas. The Four Star Spear Gobby prefers environments with a fine sand bed, which they use for sifting through in search of food. This behavior is a key aspect of their role in the ecosystem and their care in an aquarium setting.
In their natural habitat, Four Star Spear Gobies are active during the day, spending their time foraging for small invertebrates and other food particles. They are known for their unique feeding behavior, which involves taking mouthfuls of sand, sifting through it for edible material, and then expelling the remaining sand through their gills. This process not only provides them with nutrition but also helps to keep the substrate clean and aerated. The presence of a deep sand bed in their aquarium is crucial to allow them to exhibit this natural behavior. They are generally peaceful fish but can be territorial towards members of their own species, especially in confined spaces. Providing ample hiding spots and sufficient space is essential to minimize aggression. These gobies are also known to form symbiotic relationships with certain invertebrates, such as pistol shrimp, where the goby acts as a watchman, alerting the shrimp to danger, and the shrimp provides shelter in its burrow.
Setting Up the Ideal Aquarium for Four Star Spear Gobies
Creating the optimal environment is crucial for the health and well-being of Four Star Spear Gobies. Mimicking their natural habitat as closely as possible will help them thrive in captivity. A well-maintained aquarium not only enhances their vibrant colors and active behavior but also reduces stress and the risk of disease. This section will cover essential aspects of setting up an aquarium tailored to the specific needs of Four Star Spear Gobies, including tank size, substrate, water parameters, and suitable tank mates.
Tank Size and Substrate
The size of the aquarium is a primary consideration when keeping Four Star Spear Gobies. While they are relatively small fish, they require sufficient space to exhibit their natural behaviors and minimize stress. A minimum tank size of 30 gallons is recommended for a single Four Star Spear Gobby or a pair. Larger tanks are preferable, especially if you plan to keep multiple gobies or other fish species. The extra space provides ample room for swimming, foraging, and establishing territories. A larger volume of water also contributes to greater stability in water parameters, which is beneficial for the overall health of the aquarium ecosystem.
The choice of substrate is particularly important for Four Star Spear Gobies due to their feeding habits. A fine sand bed, approximately 3 to 4 inches deep, is ideal. This depth allows them to sift through the sand for food, mimicking their natural foraging behavior. Aragonite sand is a popular choice as it helps maintain a stable pH and provides buffering capacity in the aquarium. The sand bed also serves as a habitat for beneficial microorganisms and small invertebrates, which can supplement the goby's diet. Avoid using coarse substrates or gravel, as these can be difficult for the gobies to sift through and may cause injury. Regular maintenance of the sand bed is essential to prevent the buildup of detritus and maintain water quality. This can be achieved by using sand-sifting invertebrates, such as certain types of snails and sea stars, or by manually stirring the sand bed during water changes.
Water Parameters and Filtration
Maintaining optimal water parameters is crucial for the health and longevity of Four Star Spear Gobies. These gobies are sensitive to fluctuations in water chemistry, so consistency is key. The ideal temperature range for their aquarium is between 72°F and 78°F (22°C and 26°C). A stable temperature can be achieved using a reliable aquarium heater and a thermometer to monitor the water temperature regularly. The specific gravity should be maintained between 1.024 and 1.026, which is typical for a reef environment. Salinity levels should be checked regularly using a refractometer to ensure they remain within the appropriate range.
Water quality is another critical factor. Ammonia and nitrite levels should be maintained at 0 ppm, and nitrate levels should be kept as low as possible, ideally below 10 ppm. Regular water changes, typically 10-20% every one to two weeks, are necessary to prevent the accumulation of harmful substances and replenish essential trace elements. A good filtration system is essential for maintaining water quality. A combination of mechanical, chemical, and biological filtration is recommended. Mechanical filtration, such as filter sponges or socks, removes particulate matter from the water. Chemical filtration, such as activated carbon or specialized resins, removes dissolved organic compounds and other pollutants. Biological filtration, which is achieved through the colonization of beneficial bacteria in the filter media and substrate, converts harmful ammonia and nitrite into less toxic nitrate. A protein skimmer is also highly recommended for marine aquariums as it removes organic waste before it breaks down, further improving water quality.
Tank Mates and Compatibility
Choosing appropriate tank mates is essential for the well-being of Four Star Spear Gobies. These gobies are generally peaceful but can be territorial towards members of their own species or similar-looking gobies. It is best to keep them singly or in a mated pair in a sufficiently large tank. If keeping a pair, introduce them simultaneously to minimize aggression. Avoid housing them with aggressive or predatory fish that may bully or injure them. Suitable tank mates include other peaceful reef fish, such as small dartfish, firefish, and certain types of clownfish.
Invertebrates also make excellent tank mates for Four Star Spear Gobies. They are generally reef-safe and do not bother corals or other invertebrates. They can coexist peacefully with various types of shrimp, snails, and crabs. In fact, certain invertebrates, such as pistol shrimp, can form a symbiotic relationship with these gobies. The goby will act as a watchman for the shrimp, alerting it to danger, while the shrimp provides the goby with a burrow to retreat into. This symbiotic relationship is fascinating to observe and can add an extra layer of interest to the aquarium. When selecting tank mates, consider the overall temperament and needs of all the inhabitants to ensure a harmonious and thriving aquarium environment. Overcrowding should be avoided, as it can lead to stress and increased aggression.

Feeding and Diet
The Four Star Spear Gobby has a unique feeding behavior that requires careful consideration when planning their diet in an aquarium setting. In their natural habitat, they are continuous foragers, sifting through the substrate for small invertebrates, worms, and other organic matter. Replicating this feeding pattern in captivity is essential for their nutritional needs and overall health. A varied diet consisting of small, meaty foods is ideal. High-quality frozen foods such as brine shrimp, mysis shrimp, and copepods should form the basis of their diet. These foods are rich in protein and essential nutrients that support their growth and coloration.
Live foods can also be offered to supplement their diet and stimulate their natural foraging behavior. Live brine shrimp, copepods, and small worms are excellent choices. These live foods not only provide nutrition but also encourage the gobies to sift through the substrate, mimicking their natural feeding habits. Prepared foods, such as small sinking pellets or flakes, can be offered, but it is important to ensure that these foods are small enough for the gobies to consume. A feeding schedule that involves multiple small feedings throughout the day is preferable to a single large feeding. This mimics their natural foraging behavior and ensures that they have a constant supply of food. It is also important to monitor their feeding behavior to ensure that they are getting enough to eat. Four Star Spear Gobies can be slow eaters, and they may be outcompeted for food by more aggressive tank mates. Providing ample hiding spots and feeding them in a way that minimizes competition can help ensure they get their fair share.
Health Monitoring and Disease Prevention
Regular health monitoring is crucial for the well-being of Four Star Spear Gobies. Observing their behavior, appearance, and feeding habits can provide valuable insights into their health status.

These gobies are known to lay their eggs in secluded areas, and providing suitable spawning sites is crucial for encouraging breeding. Water quality is paramount in a breeding tank. Maintain stable water parameters, including a temperature between 72°F and 78°F (22°C and 26°C), a specific gravity between 1.024 and 1.026, and low levels of ammonia, nitrite, and nitrate. Regular water changes are essential to maintain water quality and prevent the buildup of harmful substances. A gentle filtration system, such as a sponge filter, is recommended to avoid disturbing the eggs or fry. Avoid using strong currents or powerheads in the breeding tank.
Courtship and Spawning
Four Star Spear Gobies exhibit a unique courtship behavior that is fascinating to observe. The male will typically display to the female by fanning his fins and performing elaborate swimming displays. He may also guard a potential spawning site, such as a cave or crevice, and attempt to entice the female to enter. If the female is receptive, she will join the male in the spawning site, and they will engage in a spawning dance. The female will lay her eggs on the substrate or on the roof of the cave, and the male will fertilize them. Four Star Spear Gobies are substrate spawners, meaning they lay their eggs on a surface rather than scattering them in the water column. The eggs are small and adhesive, sticking to the surface where they are laid. After spawning, the male typically guards the eggs, fanning them with his fins to keep them oxygenated and removing any debris. The incubation period for the eggs is usually between 4 and 7 days, depending on the water temperature. During this time, it is important to maintain stable water parameters and avoid disturbing the eggs. Removing the parents after spawning is a common practice to prevent them from eating the eggs or fry, but if the parents are not harassing the eggs, they can be left in the tank to continue their parental care.
Egg Care and Raising the Fry
Once the eggs hatch, the fry (baby fish) are very small and require specialized care. The fry of Four Star Spear Gobies are planktonic, meaning they drift in the water column and feed on microscopic organisms. Providing the fry with an appropriate food source is crucial for their survival and growth. Newly hatched brine shrimp (Artemia nauplii) and rotifers are excellent first foods for the fry. These live foods are small enough for the fry to consume and provide the necessary nutrients for their development. Maintaining water quality is also critical for the fry. Regular water changes, using aged water that matches the parameters of the fry tank, are essential. A gentle air stone can provide aeration without creating strong currents that could harm the fry. The fry will undergo several stages of development, and their diet will need to be adjusted as they grow. As they get larger, they can be offered larger food items, such as copepods and microworms. It is important to provide a varied diet to ensure they receive all the necessary nutrients. Raising Four Star Spear Gobby fry can be challenging, but with careful attention to their needs, it is possible to successfully breed these fascinating fish in captivity.
