Description:
   Rosy Barbs (Puntius conchonius) originate from the southeastern countries of Pakistan, India, Nepal and Bangladesh. They are found living in a wide variety of habitats including: streams, river tributaries, ponds, lakes and flood plains. These fish are actually quite tolerant of a wide range of water conditions and environments, which explains their widespread distribution.

   Rosy Barbs are one of the most popular and readily available fish in the aquarium hobby, for many reasons. They are an active fish with a peaceful temperament, bright color, and adult size of no more than five to six inches in length. Rosy Barbs make great additions to an aquarium, but are also great for ponds. Males have a brighter red coloration as opposed to the females that look more gold or silver than red. Both sexes have black markings on the fins and sides.

    The Rosy Barb makes a great addition to a wide variety of tropical community and river biotope aquariums. The male Rosy Barb exhibits more red coloration over a silver body, while the female is mostly all metallic silver/gold in coloration. Since Rosy Barbs are prolific breeders, commercial breeders have begun to selectively breed them in order to produce strains with very bright red coloration and with more of the red coloration spread out over the entirety of the fishes body.

   The Rosy barb are very easy to care for and can tolerate a wide variety of water conditions. However, they are a schooling species that really should be kept in groups of six or more individuals in order to maintain their natural schooling behaviors.

Tank Size : Should be 20 gallon or larger




Tank Setup :

    You can rinse the aquarium gravel with hot water and spread it in the barb's tank. Install an aquarium filter to maintain the quality of water in the tank. Attach your heater to the tank, setting it to maintain the water temperature at 65 to 77 degrees Fahrenheit (21 to 25 degrees Celsius).After that Plant some hardy aquarium plants and a few floating plants,rosy barbs are most content in a well-planted tank with some top shading that can shield them from the light shining on your aquarium. Provide your tank with some hideouts, such as driftwood and rocks.

     Rosy barbs' tank water should stay within the range of 6.0 to 7.5 pH, and water hardness should be between 2 and 10 dH. Monitor these water conditions with the aquarium test kits on a regular basis.

Tankmates:

   These fish are great community fish, socializing well with many other non-aggressive fish of similar size that enjoy cooler waters. Fish such as Swordtails, Gouramis, Angels, Knifefish, Ropefish, Paradise fish, Danios
, many American Cichlids,Tetra and other Barbs make suitable tankmates. Aquarium hobbyists have had success using Rosy Barbs as a dither fish in Cichlid tanks. Their bright colors and luminance attract shy cichlids out of their hiding spots, and because Rosy Barbs are so agile they can out swim most Cichlids around the same size.
    Avoid keeping them with tropical fish that are long-finned and slow moving. They will most likely not do well with the Rosie Barb.

Water Region: Bottom, Middle & Upper  regions of the aquarium.

Feeding: Omnivorous.

    These fish can accept all types of live & prepared foods. You can be fed flakes, spirulina, lettuce, spinach, brine shrimp, freeze dried foods, mosquito larvae etc. Rosy Barbs eat very fast, so make sure your other fish get somthing to eat. They will often nip at plants. To keep Rosy Barbs from eating your plants, try feeding them spinach (soften the spinach in hot water). They will usually ignore the other plants and go for the spinach.

Sexual Differences: Adults Easily distinguished.

    When These fish live in good condition, males are a rosy pinkish red, with black tipped fins. Females have a yellowish to silver body. Females are also rounder especially when they have eggs. Females have lighter coloured fins.


Breeding:
    Breeding Tank about this fish is about 20 or 30 gallon is optimal. Rosy Barbs will only breed in water a few inches deep, but make sure to raise fry in a bigger tank or their growth may become stunted. Allow for plenty of plants in the tank, they offer seclusion as well as a place to lay eggs.

    Females remain smaller and plumper, while males get bigger but slimmer. Females lack the brighter red coloration of the males, usually being more yellow, olive, or gold. For a breeding set up, have one male and two females. Once ready to breed, the female will change color and become more vibrant. When a male and female initiate breeding, they display behaviors of love play and mock mating. Once the females eggs are fertilized, she will scatter the hundreds of eggs into substrate, on a plant or decoration, or simply expel them into the open water. Neither parents care for the eggs after spawning, and will eat them if not separated from the tank immediately. The remaining eggs will hatch within 30 hours of being planted.
