Splash Tetra Copella Arnoldi 3cm Overview: The Splash Tetra, scientifically known as Copella arnoldi, is a captivating freshwater fish famous for its unique breeding behavior, where it leaps out of the water to lay eggs on overhanging leaves. With a slender body, subtle coloration, and fascinating habits, this species adds a touch of intrigue to any aquarium. Origin: Native to the slow-moving waters of the Amazon Basin in South America, the Splash Tetra inhabits streams, rivers, and flooded forests, where it thrives in areas with dense vegetation and overhanging plants. Feeding: Splash Tetras are omnivorous and enjoy a varied diet. They should be fed high-quality flake or micro-pellet foods, supplemented with live or frozen options like brine shrimp, daphnia, and mosquito larvae. Their natural diet includes small insects and crustaceans, so offering occasional live prey will keep them healthy and active. Tank Mates: These peaceful tetras do well in community tanks with other non-aggressive species. Suitable tank mates include small tetras, rasboras, Corydoras catfish, and dwarf cichlids. They are best kept in groups of six or more to encourage natural schooling behavior and reduce stress. Aggression: Splash Tetras are known for their peaceful nature and display little to no aggression, making them an ideal choice for community tanks. They are unlikely to bother other fish, provided they are housed with similarly peaceful species. Experience Level: Intermediate. While not difficult to care for, Splash Tetras require a well-maintained tank with specific conditions to replicate their natural habitat. Their unique breeding behavior also makes them an interesting species for more experienced aquarists to observe and potentially breed. Water Parameters: To keep Splash Tetras healthy, maintain water temperatures between 72-82°F (22-28°C), a pH of 5.5-7.0, and soft to moderately soft water (2-12 dGH). A calm tank with plenty of surface vegetation, floating plants, and overhanging leaves will help replicate their natural environment and encourage their unique breeding behavior. In summary, the Splash Tetra is a fascinating and peaceful species that adds both beauty and intrigue to a well-planned community tank. Their unique breeding habits and gentle nature make them a rewarding choice for intermediate aquarists looking to care for something truly special.
