Copeland's Tetra

Geographic Origin and Biotope: Originating from the Solimões River basin (upper Amazon River) in Brazil. Frequents floodplain lakes, oxbows, and slow watercourses within the forest, where the water is often turbid or "white" and rich in plant debris.

Taxonomy and Morphology: Copeland's Tetra (Hyphessobrycon copelandi). Species belonging to the "Rosy Tetra" clade. Tall and laterally compressed body, with a pronounced dorsal fin, typical of elegantly swimming mid-water characins.

Social Behavior: Gregarious, active, and hierarchical nature. Males engage in frequent displays of strength by puffing out their fins to intimidate rivals or impress females, without ever causing injury. Schooling is indispensable (minimum 8).

Coloration and Sexual Dimorphism: The body has a warm pinkish or reddish hue. A peculiarity is the tall, black dorsal fin with a white or pinkish apex. Females are noticeably stockier with short fins; males exhibit much more vibrant colors.

Aquarium Setup: An aquarium of at least 60-80 cm (24-32 inches). Appreciates a light or dark sand bottom, plenty of knotty wood to break visual lines, and dense planting on the sides (e.g. Echinodorus) leaving the center free for displays.

Diet and Feeding: Omnivore (Micro-predator). Willingly accepts granules and flakes. The key to developing the vibrant red coloration is a varied diet that includes abundant live or frozen food (daphnia, brine shrimp, bloodworms).

Water Quality: Flexible and hardy fish. Prefers soft and weakly acidic to neutral water (pH 5.5-7.0, GH 1-10). Water purity is vital to prevent the deterioration of the large male fins.

Compatibility and Tankmates: Excellent companion for Amazonian community tanks. Splendidly shares space with Corydoras, Loricariids, dwarf Cichlids (Apistogramma, Mikrogeophagus), and other peaceful tetras of the same size.

Aquarium Reproduction: Oviparous species. In the morning, pairs scatter adhesive eggs among bushes of fine-leaved plants (Java moss). There is no parental care; remove the adults to save the brood.

Risks and Diseases: Very robust if kept in a school. An isolated specimen will quickly waste away from stress. Moderately susceptible to Ichthyophthirius (white spot disease) in case of sudden thermal shocks.
