The Denison barb originates from parts of western India, specifically the rivers Chalakkudipuzha, Chaliar, and Kallada. Torpedo barbs are also found in designated wildlife sanctuaries in Mundakayam, Travancore, Periyar, and Kallada. Unfortunately, the Roseline shark is a victim of its own popularity, and because of overharvesting to meet demand, pollution, and deforestation, the species now on the IUCN endangered list.
In recent years, action to counter these problems has included periods when the collection of the fish is not permitted, together with some new commercial puntius denisonii breeding programs in Eastern Europe and Southeast Asia. Sahyadria denisonii adapt surprisingly well to aquarium life, although these fish are not best-suited to novice hobbyists.
The wild denisonii lives in India in rocky underwater habitats with heavy vegetation, and you can replicate that in a captive environment. In fact, a sparely decorated tank with little planting may cause the fish to lose much of their color. Although not territorial, Denison barbs are highly active, fast swimmers, and for that reason, they may not thrive in a small tank.
Ideally, your aquarium should be at least 55 gallons in capacity and long, rather than tall to allow plenty of open water for unhindered swimming. A better idea is to provide driftwood and rock caves where the fish can take cover when they want to.
When choosing a substrate for the aquarium , use sand or gravel and a few smooth stones or pebbles of different sizes for aesthetic effect. As previously mentioned, the puntius denisonii needs a fast-flowing current in the tank to thrive. You can provide that by fitting an internal power filter or external canister that has an outlet set at the surface of the water, facing down the length of the tank to produce the high levels of flow and oxygenation that these fish need.
The tailfin, however, has stripes of dark black and yellow. The striping detail can be found on the tips of both forked ends. Mature specimens will often develop a beautiful shade of emerald green on the head. The easiest way to distinguish between the two is by looking at size. Females get slightly larger than males.
Females may also have duller coloration. The average Denison Barb size is around six inches in length when fully-grown. Thanks to their large size, their color details are very visible making them a great fish to spectate.
However, it also means that you will need a sizable tank to keep them comfortable. However, their active lifestyles and sensitivity to water changes will require a bit of attention and preparation. These fish can get fairly large as adults. Not only that, but they are powerful swimmers!
Thus, you need as much space as possible. The minimum tank size requirement for Denison Barbs is 55 gallons. That should suffice for a small group of these fish. Author Note: A larger tank is always recommended if you have enough room in your home. That is especially true with active swimmers like the Denison Barb. Denison Barbs come from highly oxygenated bodies of water that are teeming with plant life.
You must replicate this environment to help your fish reach their full potential. The good news is that Denison Barbs can tolerate a generous range of parameters. As long as you stick within the acceptable ranges and avoid any major fluctuations, you should not have any major problems. We highly recommend getting a trustworthy and accurate water test kit to monitor these parameters throughout the week. Perform tests more regularly when you first get your Roseline Sharks.
As they get used to their new home, you can decrease the frequency of tests a bit. Without it, the fish can become stressed and lose its coloration. Starting at the bottom of the tank, apply a layer of sand or fine gravel. You can add some rocks and pebbles to the substrate for a more natural look. Then, add some plants.
You can choose plants like Anubias, Java Fern , and anything else that adds some vegetation to the environment. They should be kept in schools, of a half dozen or more. As a result, they are best kept only in large tanks of 55 gallons at a minimum. Other barbs, danios, larger members of the tetra family, rainbow fish, and most cichlids are suitable tank mates. The key is to keep them in a school and provide them with plenty of space. Because this species quickly grows to be quite large, they quickly outgrow even gallon tanks.
A sufficiently sized tank should have plenty of room for free swimming of some distance, as these are an active fish that needs to be on the move. Some hiding places are also recommended; rock caves or driftwood can be used. Live plants can be problematic, as they may be uprooted by darting denison barbs.
However, hardy species such as anubias can be used, if well anchored. This species is accustomed to high oxygen levels and pristine water. High levels of organic matter are not tolerated well, which means regular water changes and tank cleaning are key to keeping this species healthy.
Some water movement is necessary, which can be provided with a spray bar or powerhead. Water temperatures can be lower than for other tropical freshwater fish; however sudden drops in temperature must be avoided. Denison barbs are omnivorous and will accept many foods. For optimal health, they should be fed a wide variety including meaty foods as well as vegetable matter. Live foods will be readily accepted, including bloodworms , daphnia, cyclops , and shrimp.
Algae, spirulina, and even fresh vegetables will also be readily accepted. There are few clear differences between the sexes. However, adult females grow a bit larger, are heavier-bodied, and are sometimes less brightly colored than males. How big do clown barbs get? Size of fish - inches: 5. How big does a rainbow fish get?
Rainbowfish are usually less than 12 cm 4. They live in a wide range of freshwater habitats, including rivers, lakes, and swamps.
What do Roseline sharks eat? The Roseline Shark will eat some hair algae, BBA, and other algae types but may also feed on soft-leaved plants, but does not like anubias plants, swords or grasses.
Heavily planted tanks is where this shark will survive best. Are gold barbs aggressive? Tank Mates. Of all barbs, gold barbs are relatively calm. While these smaller barbs are not considered aggressive, they are nippy and sometimes destructive of plants and decorations. They're best described as "semi-aggressive," and should be mixed with other similarly sized fish that are short-finned and fast.
