Copella arnoldi
Common Name
Splash Tetra
Classification
Family: Lebiasinidae
Distribution
Widely distributed in the Amazon and Orinoco river basins in South America, including parts of Brazil, Peru, Colombia, and Venezuela.
Habitat
Inhabits slow-moving tributaries, small rivers, and floodplain lakes, often found near the surface among vegetation.
Maximum Standard Length
3.2 inches (8 cm).
Aquarium Size
A minimum of 24 inches x 12 inches x 12 inches (60 cm x 30 cm x 30 cm) - 54 litres is recommended for a small group.
Maintenance
Requires a well-planted tank with plenty of surface vegetation. Floating plants are particularly beneficial as they provide cover and simulate the fish's natural habitat. A dark substrate and subdued lighting will help bring out the best colors in these fish. Regular water changes are important to maintain water quality.
Water Conditions
Temperature: 75-82°F (24-28°C)
pH: 5.5-7.0
Hardness: 18-143 ppm
Diet
Primarily feeds on insects and other small invertebrates in the wild. In the aquarium, it should be offered a varied diet including live and frozen foods such as brine shrimp, daphnia, and bloodworms, as well as high-quality flake and pellet foods.
Behaviour and Compatibility
A peaceful species that does well in a community tank with other small, non-aggressive fish. Best kept in groups of six or more to encourage natural behavior. Males may display territorial behavior during breeding but are generally not aggressive.
Sexual Dimorphism
Mature males are more brightly colored and have longer fins compared to females. Females are generally plumper, especially when gravid.
Reproduction
Known for their unique breeding behavior where the male leaps out of the water to attach eggs to overhanging leaves or other surfaces above the water. The male then splashes water on the eggs to keep them moist until they hatch. A breeding tank should include suitable overhanging structures and gentle water movement. Eggs hatch in about 36-48 hours, and the fry can be fed infusoria or other suitable fry foods until they are large enough to accept larger foods.
