Dawkinsia exclamatio, commonly known as Exclamation Barb, is a beautiful freshwater fish found in the streams of India. It is an ideal choice for peaceful community tanks.
Overview
Dawkinsia exclamatio, or Exclamation Barb, is a striking fish species native to the Western Ghats of India. Known for its unique patterning, resembling an exclamation mark, this species thrives in well-maintained community tanks. It is a peaceful schooling fish and requires the company of its own kind to feel secure.
Tank Requirements
Exclamation Barb requires a minimum aquarium size of 100 liters (26 gallons) with moderate water flow and stable parameters. The ideal water temperature ranges from 22-26°C (72-79°F), with a pH between 6.5 and 7.5, and general hardness (GH) of 5-15. A well-planted tank with open swimming spaces and driftwood would provide a natural environment for this species.
Feeding and Diet
In the wild, Dawkinsia exclamatio feeds on small insects, crustaceans, and plant matter. In captivity, they accept a variety of foods, including high-quality flakes, pellets, and live or frozen foods such as daphnia, bloodworms, and brine shrimp. A balanced diet with occasional vegetable matter will ensure their well-being.
Care and Maintenance
Exclamation Barbs are relatively easy to care for, provided that regular water changes and proper filtration are maintained. They are active swimmers, so they benefit from a spacious aquarium. It is recommended to keep them in groups of at least six to promote natural schooling behavior and reduce stress.
Compatibility
These peaceful fish are best suited for community tanks with other peaceful species like tetras, rasboras, and small catfish. Avoid keeping them with aggressive or much larger species that might bully or prey on them.
Breeding
Breeding Dawkinsia exclamatio in captivity is achievable but can be a challenge. They are egg scatterers, and their breeding behavior can be triggered by increased temperature and water flow. Spawning typically occurs in the early morning, and once the eggs are laid, the adults should be removed to prevent egg predation. The eggs will hatch in 24-36 hours, and the fry can be fed infusoria or finely crushed flakes.
