Denison Barb

The Redline Torpedo Barb, also known as the Denison Barb, is prized for its striking looks: a silvery body marked with a bold black stripe and a vivid red line, plus a tail splashed with black and yellow. Native to fast-flowing mountain streams in India's Western Ghats, it thrives in cool, well-oxygenated water and shows its best colors when kept in a shoal. Growing to about 15cm, it's an active, eye-catching addition to a spacious aquarium. Because it needs stable water quality and swimming room, it suits intermediate keepers who can provide the right conditions, and it rewards that care with a lively presence in the tank.

About Denison Barb

Denison Barb (Redline Torpedo Barb): a striking Indian barb with a red line and black stripe, growing up to 15cm. Best kept in shoals; suited to intermediate aquarists.

7 things to know before welcoming a Denison Barb

  1. 1Keep in a Group

    The Redline Torpedo Barb is a strong schooling fish that becomes skittish and stressed when kept alone or in small numbers. Bring home at least six or more so they can display their natural shoaling behavior and best coloration.

  2. 2Give It Room to Swim

    This active mid-sized barb grows up to 15cm and is a constant swimmer. Since it's best kept in a group, choose a long, spacious tank that gives the whole shoal plenty of room to move.

  3. 3Keep Water Cool and Flowing

    In the wild, this fish lives in fast-flowing, oxygen-rich mountain streams in India's Western Ghats. Avoid letting the water get too warm, and use your filter to create a gentle current that mimics its natural habitat.

  4. 4Choose Active Tankmates

    Denison Barbs are peaceful and rarely aggressive, but their constant activity can stress slower or very small fish. Pair them with similarly sized, equally active species for the best results.

  5. 5Feed a Varied, Plant-Inclusive Diet

    In nature these barbs graze on algae along with other food sources. A staple of quality prepared food supplemented with vegetables or plant matter helps keep them healthy.

  6. 6Cover the Tank

    This fish can jump when startled, so a secure lid is important to prevent it from leaping out. Adding some cover or planting in the layout also helps it feel more settled.

  7. 7Acclimate Slowly and Plan Ahead

    Because this species is sensitive to sudden water changes, take extra time acclimating new arrivals. Keep in mind it will eventually reach around 15cm, so plan your tank size with its adult form in mind.

Frequently asked questions about Denison Barb

Q.Is this fish suitable for beginners?
A.The Denison Barb is generally considered suited to intermediate keepers. It has specific needs around water temperature, flow, and shoaling, so it's best attempted once you have some tropical fish experience.
Q.How many should be kept together?
A.Because they are strong shoaling fish, keeping at least six or more together is recommended. In smaller numbers they tend to become skittish and rarely show their full coloration or natural schooling behavior.
Q.How big a tank does it need?
A.Since it grows up to 15cm and swims very actively, a long, spacious tank is important, especially when keeping a shoal. Make sure there's plenty of open swimming space.
Q.Can it be kept with other fish?
A.It's peaceful and not aggressive, but its very active swimming style doesn't mix well with slow-moving fish. Tankmates of a similar size and activity level tend to work best.
Q.Is this species regulated under CITES?
A.No, the Denison Barb is not subject to CITES. That said, due to habitat decline in its native India, the IUCN lists it as an endangered species.
