About This Species
Basic Description
The Yellowfin Shiner, also known as the Lutipinnis shiner, is a small, active, and brightly colored freshwater fish from North America. They are social creatures that must be kept in groups and enjoy swimming in the middle and upper tank levels. As omnivores, they are not picky and accept various foods like flakes, pellets, and frozen or live options. Their fast-swimming nature makes them an engaging species to watch.
Detailed Description
Hobbyists should replicate this shiner's natural stream habitat with medium water flow and temperate conditions. A secure lid is mandatory, as this species is a known tank jumper. Its medium difficulty rating reflects these specific environmental needs and its active disposition. To thrive, these energetic schoolers require the company of their own kind and a varied daily diet to fuel their metabolism and maintain their bright coloration. Their waste production is relatively low, but their activity demands good filtration.
Scientific Description
Hydrophlox lutipinnis, a North American cypriniform in the family Leuciscidae, requires specific water chemistry, including a pH of 6.5-8.0 and a hardness of 89-214 dGH. This species has a medium metabolic rate and oxygen consumption, resulting in a low bioload factor of 1.6 relative to its high activity level. Successful husbandry must account for these physiological traits in a well-oxygenated system with adequate flow. Breeding is considered moderately difficult, likely requiring precise environmental triggers reflecting seasonal changes in its native habitat.
