Goby – Freshwater Northern Trout Gudgeon

Northern Trout Gudgeon Mogurnda mogurnda, commonly known as the Northern Purple-Spotted Gudgeon, is a strikingly beautiful, hardy freshwater fish native to Northern Australia and New Guinea. Belonging to the “sleeper goby” family This is highly valued by aquarists for its vibrant red and purple mottled patterns, unique personality, and hearty robust nature! Water Temp: Keep the water between 72°F and 82°F (22°C to 28°C) pH & Hardness: They prefer a stable, near-neutral pH of 6.8 to 8.0 and a water hardness of 5 to 18 dGH. Aquarium Decor: Use a soft sand substrate with plenty of rocks, bogwood, and robust live plants to create caves and lines-of-sight barriers. Filtration: They inhabit slow-moving billabongs and streams in the wild. Keep water currents and flow to a minimum. Feed them a high-protein diet consisting of frozen bloodworms, brine shrimp, mysis shrimp, and live microcrustaceans. Prepared Foods: Once settled, they will readily accept sinking carnivore pellets and high-quality granules. They generally do poorly on basic flake food. Temperament and Tank Mates: They reach a maximum length of 6 to 7 inches (15 to 17 cm) in captivity, though most stay around 4 to 5 inches.Behavior: They are free-swimming across the lower and middle water column. They can be quite boisterous, highly territorial with their own kind. House them with fast-moving or robust community fish of a similar size. Excellent options include Melanotaenia Rainbowfish, large danios, medium barbs, and tough tetras. Incompatible Tank Mates: Do not keep them with slow, long-finned fish or any small species/invertebrates (like neon tetras or dwarf shrimp), as the gudgeon will quickly view them as prey. Breeding BasicsSpawning: They are prolific, easy-to-breed benthic egg-layers. A compatible pair will form a bond, and the female will lay a clutch of 100 to 500 adhesive eggs onto a hard surface like flat stones, slate, or wood. Shipped at 1.50 – 1.74″
