The Redside Barb (Puntius bimaculatus):

Habitat and Distribution

The Redside Barb is native to the freshwater streams and rivers of Sri Lanka and parts of Southern India. Its natural habitat is characterised by clear, well-oxygenated water, often with a substrate of sand and pebbles. It prefers areas with plenty of vegetation and moderate water flow, which provides both cover and a steady supply of food.

Physical Characteristics

The Redside Barb is a relatively small fish, typically reaching a size of up to 7 centimetres (just under 3 inches).

• Colouration: Its body is a subtle silvery-gold colour with a shimmering iridescence.
• Markings: The most defining feature is a vibrant red stripe that runs from the gill cover to the base of the tail, giving the fish its common name. It also has two distinct black spots: one on its side near the centre of its body and a second, smaller one at the base of its caudal (tail) fin.
• Body Shape: It has a streamlined, torpedo-shaped body, which is well-suited for moving through flowing water.

Diet and Feeding

The Redside Barb is an omnivorous fish with an unfussy appetite, making it very easy to feed in the aquarium.

• Staple Diet: A high-quality flake food or small pellets designed for tropical community fish should be the foundation of its diet.
• Frozen & Live Foods: Supplement their diet with protein-rich foods like frozen or live bloodworms, brine shrimp, and daphnia. These supplements will enhance their colours and promote overall health.
• Vegetable Matter: They also enjoy some vegetable matter, so a flake food with a spirulina component is beneficial.

Behaviour and Temperament

The Redside Barb is celebrated for its peaceful and sociable nature. This makes it a perfect addition to a tranquil community tank.

• Shoaling Fish: Like most barbs, the Redside Barb is a shoaling species. It is crucial to keep them in a group of at least six to eight individuals. This not only makes them feel more secure and confident but also showcases their natural shoaling behaviour beautifully.
• Ideal Tank Mates: Due to their peaceful temperament, they can be housed with other non-aggressive fish of a similar size. Suitable tank mates include smaller tetras, rasboras, corydoras, and other peaceful, small barbs like the Cherry Barb.
• Avoid: They should not be kept with overly aggressive or large fish that may intimidate or predate upon them.
