Blue Eye - Fork Tail

The Blue Eye Forktail (Isbrueckerichthys alipionis), often admired for its vibrant blue eyes and distinctive forked tail, is a small, peaceful freshwater fish native to fast-flowing streams in Southeast Asia. Its unique coloration and active nature make it an attractive addition to well-maintained community aquariums. This species prefers cooler, oxygen-rich environments and is best suited for aquarists who can provide stable conditions that replicate its natural habitat. Features of the Blue Eye Forktail Compact body typically reaching 5 cm in length Striking iridescent blue eyes contrasted with a silvery-grey body Distinctive forked tail with subtle coloration Peaceful and active swimmer, prefers schooling in groups Adapted to fast-flowing, well-oxygenated waters The Best Aquarium Size for Blue Eye ForktailA minimum aquarium size of 40 litres is recommended to house a small group of Blue Eye Forktails. A longer tank layout helps accommodate their active swimming and schooling behaviour. Strong aeration and water flow are essential to mimic their natural stream environments. Tank Mate Compatibility for Blue Eye ForktailDue to their peaceful nature, Blue Eye Forktails do well with similarly sized, non-aggressive species such as: White Cloud Mountain Minnow Cherry Barb Pygmy Corydoras Harlequin Rasbora Zebra Danio Diet for Blue Eye ForktailThe Blue Eye Forktail is omnivorous and thrives on a varied diet that includes high-quality flake food, micro pellets, and live or frozen foods like daphnia, brine shrimp, and bloodworms. Feeding should be frequent but in small amounts to prevent water quality issues. Aquarium Setup for Blue Eye Forktail Aquarium FiltrationA strong filtration system with good water turnover is necessary to maintain high oxygen levels and replicate fast-flowing stream conditions. Aquarium PlantsIncorporate hardy plants such as Java Fern, Anubias, and Cryptocoryne to provide shelter and reduce stress. These plants tolerate higher flow rates well. Aquarium LightingModerate lighting is sufficient to support plant growth and enhance the fish’s natural colours without causing stress. Aquarium HeatingMaintain temperatures between 20°C and 24°C to suit their cool-water preferences. Consistent temperature control is crucial. Aquarium SubstrateUse smooth gravel or fine sand to replicate riverbed conditions and avoid injury. Aquarium DecorationsAdd natural elements like driftwood, smooth stones, and leaf litter to create hiding places and mimic the Blue Eye Forktail’s native habitat. These features also encourage natural behaviours.
