Defined Tag: Types of Fish.

This breed is commonly known as Spraying Characin. The fish grows around 3 inches in size and comes from Guiana, Venezuela, and Brazil. Sprays have elongated fins, as well as a slim body. Spraying Characin feeds on all foods and prefers neutral or soft water conditions.

How do Opella Arnoldi fish breed?
Spraying Characin spawns on the surface of overhanging leaves. In addition, the fish may spawn at bottom surface area of the aquarium. Spraying Characin prefer to breed in thinly planted aquariums, whereas around 15 gallons of water is added. The level is usually 1 ½ inches below the glass cover. This fish only produces around 15 eggs, which the fish will fall back into the water once the eggs are deposited. In addition, the fish will repeat this procedure until around one hundred eggs are deposited.

How are the Opella Arnoldi eggs maintained?
Once the fish spawn, remove the female fish from the tank. Contrary to mother natures arrangement the male handles egg care. The male will splash water over the eggs. If the eggs fall into the water however, the male fish will feast on the hatch. If you notice the male attempting to eat the eggs, remove him also from the tank.

Once you remove the male from the tank, fix an aerator stone in the tank. The stones will promote spray to bubble, which will maintain the health of the eggs. Lastly, you want to remove the male fish again around the fourth day, since the fry will seep into the waters.
