Flowing fins change the whole character of a rosy barb. This long-fin form of Barbus (Puntius) conchonius keeps the species' working-class toughness and adds extended finnage that turns every change of direction into a flourish — the rosy colouring of the standard fish, carried on a far more elegant frame.
Underneath the fins, the care profile is reassuringly simple. The record rates it easy: around 6 cm at adult size, about five years of lifespan, and a 100-litre minimum aquarium. It prefers things cooler than the tropical default — 20 to 24 °C — with pH between 6.5 and 7.8 and hardness from 5 to 15 dGH, which makes it an economical fish to heat as well as an easy one to please. An omnivorous diet means it accepts a wide range of foods without fuss, and it holds the middle region of the tank, where those trailing fins are seen at their very best.
Temperament deserves one line of honesty: the record lists this form as semi-aggressive, with territorial behaviour possible around breeding. Keep it busy among lively tankmates and that energy has somewhere harmless to go. Those extended fins are also the reason the avoid list below reads the way it does: a long-finned fish among nippers loses condition fast, and a semi-aggressive barb among slow tankmates causes the same problem in reverse. Follow the stocking guidance to the letter rather than treating it as a loose suggestion.
Long-fin rosy barb requirements
- Easy care; adult size about 6 cm; lifespan around 5 years
- Aquarium from 100 litres
- 20–24 °C; pH 6.5–7.8; hardness 5–15 dGH
- Omnivore — feeds readily across the whole menu
- Semi-aggressive; can be territorial when breeding
Stocking around those fins
Sound companions are active fish of a similar size: danios, rasboras, rainbowfish, Corydoras and loaches. The avoid list matters here — slow-moving fish, long-finned tankmates that invite nipping, very small fish or fry, shrimp and other tiny invertebrates, and aggressive territorial cichlids should all stay off the plan. Your fish are packed for transit with a licensed live-animal courier and travel under a live arrival guarantee.
