The Neon Rosy Barb is one of the most colorful varieties developed from the popular Rosy BarbPuntius conchonius. This variety is truly striking with its glowing rosy body. A school of these illuminated beauties are fun to watch because they are constantly on the move. They are just one of several varieties developed from the Rosy Barb, others include the Long Fin Rosy Barb, Red Glass Rosy Barb, and Gold Neon Rosy Barb.
These colorful fish are hardy and undemanding and will give any aquarium an energetic boost. Like all the varieties of the Rosy Barb, they enjoy the companionship of 4 - 6 others to school with. They are always active so need plenty of room to swim. Being peaceful, they will do well in a community aquarium with only an occasional nip on a tankmates fins. These fish also prefer cooler water, 64-72° F (18-22° C), and you should select tankmates that will also thrive in cooler temperatures.
These barbs are a good choice for beginning fish keepers, but will make a dynamic display in any aquarists aquarium. They are a good sized Cyprinid that will reach up to about 4 inches (10 cm) in length in the aquarium, though wild populations of its parentage can reach up to about 6 inches (15 cm). A school of this variety will need at least a 20 gallon aquarium but being very active they'll do better in a larger tank. A tank that is 20 inches long and 30 or more gallons is ideal. These guys are great jumpers too, so be sure the tank is securely covered.
A school of these delightful fish display some very interesting behaviors. The males will spend most of their time swimming around each other displaying, spreading out their fins to show their best colors. Like all of the varieties of this species they are prolific breeders and when spawning, the males' colors will intensify. To successfully spawn, they will need a breeding tank with shallow water that is just a couple of inches deep.
The Rosy Barb Puntius conchonius (previously Barbus conchonius) was described by Hamilton in 1822. They are found in northern India, Bangal, and Assam. There are also feral populations in Singapore, Australia, Mexico, Puerto Rico and Colombia.
These barbs occur in a variety of habitats from in swift moving rivers and streams, to ponds and backwater. They are omnivorous and feed on insects, diatoms, algae, small invertebrates and detritus. This species is listed on the IUCN Red List as Least Concern (LC). They are widespread and common in their range with no major identified threats.
The Neon Rosy Barb is a captive bred color morph developed from the Rosy Barb. Many of these barbs are captive bred for the aquarium industry. Other varieties include the Long Fin Rosy Barb, Red Glass Rosy Barb, and Gold Neon Rosy Barb. There are no wild populations of this variety.
Scientific Name: Puntius conchonius
Social Grouping: Groups
IUCN Red List: NE - Not Evaluated or not listed - There are no wild populations of this color morph.
The Neon Rosy Barb has a torpedo shaped body and its tail is forked. It has only one dorsal fin. Lacking an adipose fin, a second dorsal fin to the rear of the first, is a characteristic of all the Cyprinid fishes. This is a good sized fish that will reach about 4 inches (10 cm) in the aquarium. They are mature at 2.5 inches (6 cm) and have an average lifespan of about 5 years.
The general coloration is silvery or coppery pink body with males being a more reddish color. There is a black spot just in front of caudal peduncle, and there may be some black along the top margins of the anal and dorsal fins. When spawning, the males color intensifies to a deep rosy red or a purplish red.
Size of fish - inches: 5.9 inches (15.01 cm) - In the wild the regular Rosy Barb can reach up to 6 inches (15 cm), but these captive bred varieties generally only reach about 4 inches (10 cm) in length.
Lifespan: 5 years
Fish Keeping Difficulty
The Neon Rosy Barb is a delightful addition to most any tank, and is a great choice for beginning aquarists. They are hardy, handle changes in their water conditions very well, and will readily accept aquarium fare. Take care to pick tankmates that will thrive with these fish. Companions must be able to handle the cooler temperatures this barb needs, and they need to be active. This barb will on occasion nip the fins of slow swimming and long finned tankmates.
Aquarium Hardiness: Very Hardy
Aquarist Experience Level: Beginner
Foods and Feeding
Since they are omnivorous the Neon Rosy Barb will generally eat all kinds of live, fresh, and flake foods. To keep a good balance give them a high quality flake food everyday. Feed brine shrimp (either live or frozen) or blood worms as a treat. Supplement with color foods for best results in appearance. When offering food just once a day, provide what they can eat in about 5 minutes. When offering food several times a day, offer only what they can consume in 3 minutes or less at each feeding.

These barbs are easy to care for provided their water is kept clean and kept at the proper temperature. Aquariums are closed systems and regardless on size all need some maintenance. Over time decomposing organic matter, nitrates, and phosphate build up and the water hardness increases due to evaporation. Replace 25 - 50% of the tank water at least once a month. If the tank is densely stocked 20 - 25% should be replaced weekly or every other week.
Water Changes: Monthly - It the tank is densely stocked the water changes should be done every other week.
The Neon Rosy Barbs are lively fish that will swim in all parts of the tank. They are also good sized, reaching up to 4 inches in length. A school will need at least a 20 gallon aquarium, but because they are very active swimmers a tank that is 30 inches long and 30 gallons or more is ideal. They prefer cooler water at between 64-72° F (18-22° C). Additionally, the tank should be securely covered as these fish are skilled jumpers and will probably do so if given the opportunity.
As with most barb species, an aquarium best suited to them will have plenty of room for swimming, a soft bottom, and plants around the edges. A sandy substrate, dense vegetation, and drift wood will encourage their most effective displayed. Try to plan for one or two hours of sunlight hitting the tank as the illumination will make the fish even more stunning. An efficient filter and good water movement are needed for the male fishes to develop their coloration.

Breeding / Reproduction
The Neon Rosy Barb is moderately easy to breed and become sexually mature when they have attained a size of 2.5 inches (6 cm). Select breeding pairs from the school that have excellent markings and strong color. They are egg layers that scatters their eggs rather than having a specific breeding site. The eggs are adhesive and will fall to the substrate.
These fish can spawn in a 5 to 10 gallon breeding tank with very shallow water, just a few inches deep, with a temperature between 73 - 77° F (22 - 25° C). Use a coarse gravel on the bottom or a divider that allows the eggs to pass through to protect them. Put one male in with two females in a breeding tank. The spawn is preceded with mock matings and courting, and then several hundred eggs will be laid. After the spawn, remove the parents as they will eat the eggs it they can reach them.
The eggs will hatch in about 30 hours. Free swimming fry can be fed infusoria, a liquid fry food, or newly hatched baby brine at least three times a day. Pay close attention when feeding, as foods if uneaten can quickly foul the water. The fry will require clean water to survive. See the description of breeding techniques in: Breeding Freshwater Fish: Barbs. Also see Fish Food for Fry for information about types of foods for raising the young.
Ease of Breeding: Easy
Neon Rosy Barbs are extremely hardy so disease is not usually a problem in a well maintained aquarium. They are primarily susceptible to Ich if good water quality is not provided. Anything you add to your tank can also bring disease. Not only other fish but plants, substrate, and decorations can harbor bacteria. Take great care and make sure to properly clean or quarantine anything that you add to an established tank so not to upset the balance.
A good thing about these barbs is that due to their resilience, an outbreak of disease can often be limited to just one or a few fishes if you deal with it at an early stage. The best way to proactively prevent disease is to give your Barb the proper environment and give them a well balanced diet. The closer to their natural habitat the less stress the fish will have, making them healthier and happy. A stressed fish will is more likely to acquire disease.
These fish are very resilient, but it is recommended to read up on the common tank diseases. Knowing the signs and catching and treating them early makes a huge difference. For information about freshwater fish diseases and illnesses, see Aquarium Fish Diseases and Treatments.
The Neon Rosy Barb is readily available in pet stores and online, and is reasonably priced. Females are generally less than males.
