Species Summary
The Denison Barb, scientifically known as Sahyadria denisonii, is native to the Western Ghats of India where it can be found in rivers and streams with fast-flowing water.
It was previously classified under the name Puntius denisonii but was later reclassified.
This species is highly adaptable and has become popular among aquarists around the world.
Despite its delicate appearance, they are surprisingly hardy and can thrive in a well-maintained aquarium.
Appearance
The Denison Barb is truly a sight to behold with its vibrant colors and sleek body.
It has a torpedo-shaped body, which allows it to effortlessly glide through the water.
The fish typically grows to a size of 4 to 6 inches (10 to 15 cm), making it a medium-sized species suitable for a variety of aquarium setups.
The Denison Barb is characterized by its striking red and silver stripes that run horizontally along its body from the head to the tail.
The red stripes contrast beautifully with the silver coloration of the rest of the body.
The fins are translucent and complement their overall vibrant appearance.
Sexual dimorphism is present in this species, with the males exhibiting brighter colors and longer fins compared to the females.
The males tend to have a deeper red coloration and longer dorsal fins, while the females have a more subdued hue and shorter fins.
Lifespan
If properly cared for, they can live for up to 5 years in captivity.
To ensure that your Denison Barbs live a long and healthy life, provide them with a well-maintained aquarium and a balanced diet.
Behavior & Temperament
Denison Barbs are known for their active and energetic nature.
They are generally peaceful fish but can become territorial and aggressive towards each other if kept in small groups or in inadequate tank conditions.
To promote harmony in the aquarium, it is recommended to keep them in groups of at least six individuals.
This species also exhibits a hierarchy within the group, with dominant individuals asserting their authority over weaker ones.
These fish thrive in a community tank that includes other peaceful and similarly sized fish.
They should not be paired with aggressive or fin-nipping species, as their flowing fins can be tempting targets.
Denison Barbs prefer swimming in the mid to upper levels of the tank and appreciate plenty of open space for their energetic swimming behavior.
Denison Barb Care
Proper care is essential for the health and well-being of Denison Barbs.
They require a well-maintained aquarium with suitable water parameters, a balanced diet, and a suitable tank size.
Tank Size
Due to their active nature and medium size, a minimum tank size of 30 gallons is recommended for a small group of Denison Barbs.
Providing ample swimming space is crucial, as these fish love to dart around and explore their environment.
A larger tank is always better, as it allows for a more natural and spacious habitat.
Water Parameters
Denison Barbs require specific water parameters to thrive in captivity.
- Water Type: Freshwater
- Temperature: 72-79°F (22-26°C)
- pH Level: 6.5-7.5
- Water Hardness: 5-10 dGH
Regular water testing and maintenance should be performed to ensure optimal water quality for these fish.
Tank Setup
To recreate the natural habitat of Denison Barbs, provide them with a well-decorated and planted aquarium.
In the wild, they inhabit rivers and streams with fast-flowing water and rocky substrate.
For substrate, a mix of sand, gravel, and small rocks can mimic the natural environment of these fish.
Adding driftwood and rocks to the tank not only provides hiding spots but also allows the fish to explore and establish territories.
Plants are an essential component of their tank setup, as they provide cover and oxygenation, and mimic the natural riverbed environment.
Opt for plants that can tolerate higher flow rates, such as Anubias, Java Fern, and Vallisneria.
Water flow should be moderate to mimic the fast-flowing rivers where Denison Barbs originates from.
This can be achieved with the use of a suitable filtration system or the placement of a powerhead in the aquarium.
Food & Diet
Denison Barbs are omnivorous and require a varied diet to meet their nutritional needs.
In the wild, they feed on small insects, algae, and plant matter.
In captivity, a balanced diet can be achieved by offering a combination of high-quality flakes, pellets, and frozen or live foods.
Feed your Denison Barbs a mixture of flake or pellet food as their primary diet.
Supplement their diet with frozen or live foods such as bloodworms, brine shrimp, and daphnia to provide them with essential nutrients and mimic their natural feeding habits.
Avoid overfeeding, as they have a tendency to constantly graze on food.
Feed them small portions a few times a day to prevent overeating and maintain good water quality in the aquarium.
Tank Mates
Denison Barbs are generally peaceful and can coexist with a variety of tank mates.
But choose compatible species that share similar temperaments and requirements.
Here are some suitable tank mates for Denison Barbs:
- Neon Tetras
- Corydoras Catfish
- Harlequin Rasboras
- Cherry Barbs
- Kuhli Loaches
- Otocinclus Catfish
- Gouramis
- Dwarf Cichlids
- White Cloud Mountain Minnows
- Zebra Danios
When selecting tank mates, consider the size, temperament, and water parameters of both the Denison Barbs and the potential tank mates.
Avoid pairing them with aggressive or fin-nipping species to prevent stress and potential injury to your Denison Barbs.
Breeding
Breeding can be challenging and requires specific conditions to trigger reproduction.
They are egg scatterers, meaning they release their eggs into the water column, where they are fertilized by males.
To encourage breeding, provide your Denison Barbs with a well-established planted aquarium, a balanced diet, and suitable water conditions.
Spawning typically occurs during the rainy season in their natural habitat, which can be emulated by gradually reducing the water temperature and performing regular water changes.
Separate breeding tanks with fine-leaved plants, such as Java Moss or spawning marbles, can be used to collect the eggs and protect them from being consumed by adult fish.
After spawning, the adults should be removed from the tank to prevent them from eating the eggs.
The eggs typically hatch within 24 to 48 hours, and the fry can be fed infusoria or commercial liquid fry food until they are large enough to consume crushed flakes or baby brine shrimp.
