The transparent to translucent body of the fish (except the pigmentation) helps it stay almost invisible to its predators.Any other bigger carnivorous species of animals under water can as well prey upon the neon tetras. Predatorsīigger fishes can pose threat to the tiny, peace-loving neon tetras. However, they might at times bicker amongst themselves, but that doesn’t lead to anything more than torn fins. Neon tetras love to live in such regions under water, where there is plenty of hiding places. These tetras can at times shoal with its close relative, the cardinal tetra. If a neon tetra happens to toss out of its shoal, it becomes very stressed and spends most of its time hiding and refrain from consuming food, which might in turn make it gradually fall sick. They are social and gregarious animals and live and roam around in shoals of at least a hundred individuals in the group. These fish are peaceful and non-aggressive by nature. They feed upon insect larvae, algae and other tiny invertebrates.
In the wild, the neon tetras are omnivorous. In the wild, the largest concentration of this fish may be found in the Amazon River Basin. The neon tetra is distributed throughout the northern Latin America, including western Brazil, eastern Peru and southeastern Colombia. Recent hybrids of these fish are available in a long-fin variety. Tail and Fins: The fish has the same number of fins like most other fish, but they are transparent, and so is its tail. The neon tetras have a spindle-shaped body with a blunt nose. All the internal organs, including the skeletal system, are visible through their transparent head and body. Head and Body: Basically, the fish is totally transparent except for their colorful markings. There are also two red stripes from the middle of the body down to its caudal fin, and most of the individuals develop an olive green sheen, that lines their back.
From its nose to the bottom of the adipose fin run two blue horizontal stripes dividing it into two equal horizontal halves. Although, some individuals have been found to grow up to 2.5 inches.Ĭolor: The most striking characteristic of the fish is its bright coloring, especially its greenish-blue iridescent hue. Size: The neon tetra can acquire a maximum size of 1.5 inches.
