Description
Atlantic Mudskipper
Scientific Name: Periophthalmus barbarus
Common Names: Atlantic Mudskipper, African Mudskipper
Overview
The Atlantic Mudskipper (Periophthalmus barbarus) is a species of mudskipper found in coastal areas along the western and central African coasts, particularly in estuaries, mangroves, and mudflats. Known for its remarkable ability to survive in both aquatic and terrestrial environments, the Atlantic Mudskipper is an amphibious fish that uses its powerful pectoral fins to “walk” on land. This species is popular among aquarists who enjoy keeping brackish water setups and want to observe the unique behaviors of amphibious fish. The Atlantic Mudskipper is smaller than some of its relatives but still has a striking appearance with its large eyes and ability to leap out of the water.
Key Information
Size: 4–6 inches (10–15 cm)
Lifespan: 5–8 years (with proper care)
Diet: Omnivore
Temperament: Peaceful, territorial during breeding
Habitat & Setup
Habitat: Atlantic Mudskippers are typically found in estuaries and mangrove regions where they can move freely between water and land. They thrive in environments with both aquatic and terrestrial elements, including muddy substrates, rocks, and mangrove roots.
Tank Size: Minimum 40 gallons (151 liters) for a small group. A larger tank (55 gallons or more) is recommended for more than one individual.
Substrate: Mud, sand, or a combination of both is ideal. They need a firm substrate to walk on when out of the water, and the substrate should be deep enough to allow for burrowing.
Shelter: Provide plenty of hiding spots, such as rocks, driftwood, or caves. Mudskippers enjoy having both water and land areas in the tank, with shallow water for swimming and exposed land areas to rest and forage.
Water Conditions:
Temperature: 75–82°F (24–28°C)
pH: 7.5–8.5 (slightly alkaline)
Hardness: Medium to hard water (8–12 dGH)
Salinity: Brackish water (specific gravity 1.005–1.015)
Water Flow: Low to moderate flow is ideal, replicating the slow-moving waters of mangroves and mudflats.
Lighting: Moderate to bright lighting is best, as these mudskippers naturally live in areas where sunlight is abundant.
Diet & Feeding
Diet Type: Omnivore
Suitable Foods:
Small crustaceans (shrimp, amphipods)
Insects, larvae, and worms
Algae and detritus
Fish and small mollusks
Frozen or live foods such as brine shrimp and bloodworms
Feeding Frequency: Feed 2-3 times per week with a variety of foods. Mudskippers are opportunistic feeders and will forage for food on both land and in water.
Additional Notes: Provide a mix of both plant and animal matter to ensure a balanced diet. Mudskippers also enjoy hunting for food on land, so consider offering food on the terrestrial part of their habitat as well.
Care Notes
Activity Level: The Atlantic Mudskipper is very active, especially when it has access to both land and water. It enjoys walking and leaping on the land while occasionally swimming in the water.
Social Nature: While they are generally peaceful, Atlantic Mudskippers can become territorial, especially during breeding. It’s best to keep one male with several females in the same tank to reduce aggression.
Health: Ensure that their tank conditions are stable, particularly salinity and temperature, as fluctuations can cause stress and health problems. Regular water changes are necessary to maintain water quality in a brackish setup.
Tankmates: Atlantic Mudskippers are best kept with other peaceful brackish species that can tolerate similar water conditions. Avoid housing them with aggressive fish or species that may damage their delicate fins. Suitable tankmates include other mudskippers, small gobies, and peaceful bottom dwellers.
Fun Fact
The Atlantic Mudskipper is capable of “walking” across land using its pectoral fins. This unique behavior allows it to travel between pools of water or across mudflats in search of food or shelter. They can also leap out of the water to escape predators or move quickly on land. Their large, upward-facing eyes are adapted for seeing both above and below the water’s surface, helping them keep watch for both threats and prey.
