Copella

Copella is a genus of freshwater fish in the Lebiasinidae family. They are commonly known as splash tetras or splashing tetras. The genus is native to South America, specifically the Amazon River basin and the Guiana Shield. The most well-known species in the genus is the Copella arnoldi, also known as the splashing tetra or splash tetra.

Behavior

Copella species are known for their unique reproductive behavior, which involves the male splashing water onto a flat surface above the water level, such as a leaf, where the female has laid her eggs. This behavior is believed to keep the eggs moist and oxygenated until they hatch.

Species

There are currently seven recognized species in the genus Copella:

• Copella arnoldi (Regan, 1912) – Splashing tetra
• Copella callolepis (Regan, 1912)
• Copella compta (Eigenmann, 1914)
• Copella eigenmanni (Regan, 1912)
• Copella meinkeni (Zarske & Géry, 2006)
• Copella nattereri (Steindachner, 1876)
• Copella vilmae (Zarske & Géry, 2006)

In the Aquarium

Copella species are popular in the aquarium trade due to their unique behavior and attractive coloration. They are generally peaceful and do well in community tanks with other small, non-aggressive fish. They prefer a well-planted tank with plenty of hiding spots and a gentle water flow.

Diet

In the wild, Copella species feed on small invertebrates and insects. In the aquarium, they will accept a variety of foods, including flake food, frozen food, and live food such as brine shrimp and daphnia.

Breeding

Breeding Copella in the aquarium can be a challenge due to their unique reproductive behavior. The male will select a suitable surface above the water level and attempt to entice a female to lay her eggs there. Once the eggs are laid, the male will splash water onto them to keep them moist. This behavior can be difficult to replicate in the aquarium, but it is possible with careful observation and the right conditions.
