Facts About the Roseline Shark
The Roseline shark is known to scientists as Puntius denisonii. However, they are commonly known to laymen as Dension Barbs, Red Line Barbs, Torpedo Barbs, or Red Line Torpedo Barbs. Despite the name used, these are all the same species and fall within the Cyprinidae family. The Roseline shark has become very popular to fish hobbyists, with many people adding them to their tanks. Despite their recent popularity, they have been known to scientists since 1865. Throughout this article we will explore all you need to know about the Roseline shark.
These sharks originated in South India and are typically found in streams that are fast flowing. However, as of late they have become very popular in your freshwater aquariums. In terms of appearance, this small shark tends to be about five and a half inches long, regardless of sex. In color, they are generally gold, black, white, and red. A red line (hence one of the common names) is actually observable on their bodies, as well as a black line that runs the length of their tails. Furthermore, their body is torpedo-shaped and their tails are forked. Their lifespan is said to be anywhere between five and seven years; however, this is not properly documented and should merely be used as an estimate.
When found within an aquarium you will typically find this fish in any area of the tank. It is not like bottom-dwellers or hiders. Instead, these fish are extremely active and are frequently seen throughout the entire tank. However, due to their high levels of activity, it is essential that you only try to house these fish if you are able to provide a relatively large cage. Furthermore, it is recommended that you provide rocks, hiding places, and plants throughout the aquarium while still ensuring there is a good bit of open space for their increased activity levels. These fish travel in schools and are a very peaceful species, despite what you would generally think by their names. As a result, they make great tank mates with other fish.
The Roseline shark is an omnivore and is incredibly easy to feed. They will eat just about anything that is placed within the aquarium in terms of your typical fish food—flakes, pellets, frozen foods, etc. Believe it or not, they will even consume different varieties of vegetables as well as fruits. However, it is essential to understand that as a result, these sharks may eat your live aquarium plants occasionally.
As a result, of their uniqueness and activity, it is recommended that the tank you house these fish in be around fifty gallons. Furthermore, since they are schooling fish you should purchase more than one for your tank. Another important thing to understand in terms of care is their preference for tanks with a nice current to increase the oxygen level within the water. Driftwood is another commonly used item within tanks containing a Roseline shark group. Again, they are highly active and will chase one another around the aquarium making swimming space (and hiding spots) essential for their happiness.
In conclusion, the Roseline shark is a great addition to many aquariums, specifically tanks that are large, contain live plants, and are spacious. These sharks like to stay in groups and will be found very active during the daytime hours. Furthermore, feeding is a breeze—these sharks will truly eat just about anything. However, they are relatively expensive since most are brought out of the wild into captivity, which has also brought up the topic of extinction concerns regarding this fish being so popular in fish trading. In the end, anyone wishing to add these sharks to their aquariums should make sure they have a large aquarium equipped with driftwood, plants, and hiding spaces to meet their needs.
