One of the fundamental laws of the natural world birds live on the trees, Fish live in water. Although this particular fish bends this rule of nature and hatch their eggs on the tree. Copella Arnoldi fish is usually referred to as splashing tetra or splash tetra because of its unusual reproductive behaviour.
The splash tetra has an elongated body. The body colour is olive green to brown, and the belly is white. A stripe, slightly darker than the body colour, extends from the gill cover to the caudal fin. A thin copper-coloured line runs right above the more coloured band. A black band extends from the snout, through the eye, and to the gill cover. In favourable water conditions, the upper half of the iris will develop an eridesent orange colour. Size and length of males are 9 cm (3.5 inches) and females are 7 cm (2.8 inches). Their food is live, small flying insects, insect larvae and brine shrimp.
Splashing fish lays its eggs out of the water. It’s one of the few known species of fish in the world to do so. When the male is ready to mate, he takes up a spot in the water below an overhanging tree leaf. These fish have been born out of the water. When the male is ready to mate, he takes up his place in the water beneath the overhanging vine. It’s a little series, and if she’s interested, she ‘s going to sidle up next to him. Then they’re going to climb out of the water together. They tie their fins to the bottom of the leaf.
The female releases 8 to 10 eggs and the male fertilises them quickly until they fall back into the water. This cycle is repeated several times by the pair until numbers reach about 200 eggs. The male has responsibility’s to keep an eye on the eggs and engage in brood care by splashing water on the eggs every 10-15 minutes. For about 48 hours, when the fry hatch, they fall into the water below, where they hide as best they can. Splash tetra lives near the banks of slow-moving rivers with dense vegetation. South America; in Guyana, and the Rio Para .The fish has a life expectancy of about three years.
