Ornatus

If you have ever been to a pet store and looked into the aquarium section, you have probably seen these fish. Ornatus are a whole group of small, very active creatures that are easily recognizable by their characteristic dark spot on their tail and often brightly colored fins.

These fish come to us from the slow-flowing rivers and streams of South America. They are ideal for beginner aquarists because they are generally undemanding. But in order for them to truly reveal their beauty and live long, it is important to know a few key points about keeping them.

In this article, we will explain in simple and understandable terms what types of ornatus there are, how to create a comfortable home for them in your aquarium, and who they are best to live with. You will understand why these small, fast-moving fish are so loved around the world.

Habitat in nature

Ornatus is native to Central and South America. Its natural habitat is shallow standing water in lakes or backwaters in small rivers. Aquarists call ornatus the phantom fish or red tetra. They are similar in body shape, requirements, and character.

Description

Similar characteristics for all types of phantoms: a flat body compressed on the sides, measuring 4 to 6 cm, wide in the middle: from the dorsal fin to the belly. The dorsal fin is narrow and high, shaped like a flag. The anal fin extends from the middle of the body to the tail. A little closer to the head, at some distance from the anal fin, there are pelvic fins, which are also noticeable and bright. The tail is bifurcated, with long outer rays at a large angle to each other, which makes the tail look wide but small.

Types

There are several varieties of phantom fish, which differ in color, size, and even behavior. Most species are the result of selective breeding. In all fish, sexual differences are expressed in the shape and size of the fins.

• Ornatus vulgaris has an elongated body, a bronze-pearl hue, and is translucent. There are two red dots on the tail, and the pectoral fins also have a red tint. The dorsal and anal fins are small and harmonious in size. They can be red or the same color as the body. There is a black spot on the dorsal fin, framed in white. There may be white markings on the tips of the fins. Sometimes there is a black border on the fins and a black vertical stripe behind the gills. This is a sign of natural coloration and is rarely found on sale.

• Red phantom (red ornatus) – the main body color is cold red (ruby), saturated on the muzzle, becoming more transparent towards the tail. The tail is black, with a white or translucent silver border. Males have a black spot on the dorsal fin. Behind the gills, there is an elongated black spot bordered with golden pink. These fish are bright, but more demanding on water parameters than others.

• Black Phantom (black ornatus) – has a gray-silver translucent body, the color becomes more intense closer to the tail. The tail is black, and the other fins match the color of the body. There is a short, oblong black spot on each side behind the gills, and the gills themselves are reddish under the eyes. The dorsal fin is lush and high, serving as a decoration and distinctive feature of the fish.

• White-finned ornatus – appearance is similar to the common phantom, except that the black spots are replaced by white ones, and the fins themselves are slightly more transparent.

• Pink ornatus – similar to the common ornatus, but lighter in color and without characteristic spots. The main color is pinkish, with fins of the same color and faint red markings.

• Rubrostigma (red-spotted ornatus) – the body is colored a pale silver shade, and thanks to its translucency, a reddish spine shines through the scales. There are red markings at the base of the caudal fin and on the gills. In the center of each side, there is a small, clearly defined pink spot. The rim around the eye is also marked with a pink dot.

There are several fish whose names include the word “ornatus,” but the fish themselves have no physiological or morphological connection to the common phantoms.

• julidochromis ornatus – a small cichlid with an elongated body and a nasty predatory temperament;
• pseudotropheus elongatus (elongatus ornatus) is also a cichlid with the aggression, habits, and character typical of this family.

Keeping and care

Setting up an aquarium does not require any special skills, the main thing is to maintain a stable water environment. Maintaining the parameters that the fish are accustomed to is the owner's main task.

Setting up the aquarium

• The volume of the aquarium is calculated using the formula 10-12 liters per fish. Since ornatus are schooling fish, an aquarium of 60 liters or more is suitable for a group of 6 fish (minimum number).
• The lighting should be dim, just enough to illuminate the aquarium. If you are setting up a planted aquarium, for which light parameters are important, make sure to include plants with broad leaves that create shade.
• Any substrate is suitable, as ornatos are not particularly interested in it. The main thing is to clean it regularly with a siphon, as food debris stuck between the stones deteriorates the water quality.
• Plants (they should be planted so that there is space for swimming), grottos, and piles of stones that create shaded corners can serve as decoration. Driftwood is well suited for softening the water.
• A cover is desirable.

Water parameters

• The water temperature should be 20-24°C. The temperature must be stable, and sudden changes should be avoided.
• Hardness 3-12dgH;
• Acidity 5.5-8.0 pH;

Filtration and aeration

• A filter with adjustable pressure is suitable: phantoms do not like currents very much. Aeration is best organized separately from filtration, using a special compressor;
• Water purity should be maintained by regular water changes (1-2 times a week up to 25% of the volume, depending on the ratio of volume to number of fish). When changing the water, pay attention to the temperature of the fresh water: it should be identical to the aquarium water;

Ornathes are ancient predatory animals that lived at the end of the Permian and beginning of the Triassic periods, a couple of tens of millions of years before the appearance of dinosaurs. They look like lizards, but in fact are closer to mammals in structure. These animals were among the first large carnivorous land vertebrates, with powerful jaws and sharp teeth. Ornithopeds are an important link in evolution, showing how the characteristics of modern animals gradually formed.

Feeding

To ensure that the fish receive all the necessary micronutrients, protein, and vitamins, it is best to feed them a mixed diet. The main diet consists of dry food for tetras: its shape is easy to grasp, and its composition is balanced. Additionally, small amounts of protein are needed – bloodworms, coretra. Fish that lack vitamins may eat plants, which is unacceptable in a herbivorous environment.

Behavior and compatibility

The description of ornatus suggests that this fish is peaceful. It is similar in temperament to neons, rasboras, and guppies. Although it is considered a schooling fish, under satisfactory conditions without stress, phantoms swim on their own. They only gather in groups when there is danger or an irritating factor. Phantoms that swim in a school constantly signal with their behavior that there is a source of stress in the biotope, which means that the fish are uncomfortable and will not live long. Ornathus live in a home aquarium for 3-5 years, and their lifespan directly depends on the amount of stress they experience.

The ideal neighbors for ornate cichlids are phantoms themselves and most peaceful small catfish. In addition, tetras, pecilias, pulcheras, and swordtails are suitable for cohabitation.

Large predators, small predators, and fish that are too fast and restless are not suitable. They pose a threat to the moral and physical existence of ornate fish.

Reproduction and breeding

To breed ornate cichlids at home, you will need a spawning aquarium with the following parameters:

• Volume 30 l, water level 15-17 cm;
• Temperature 26-28 °C;
• Hardness 1-5 gH;
• Acidity 5.5-6.5 pH;
• There is no artificial lighting, and the aquarium must be covered from natural light.
• Javanese moss;
• Mesh at the bottom.

Spawning requires a school of fish with a 1:1 sex ratio. How to determine the sex of ornate fish: males usually have a sharp and large dorsal fin, and sometimes all other fins are larger than those of females. Females have a more rounded body shape with a prominent abdomen.

Reproduction should begin with dietary adjustments at least two weeks before the expected spawning. Fantoms are transferred to live food with a high protein content. They are then transferred to a special aquarium, where spawning should begin within 24 hours.

During spawning, the female lays eggs on Java moss leaves or on a net through which the eggs fall to the bottom. After spawning, the fish are transferred to a common aquarium. The fry are fed with live dust, artemia nauplii, infusoria, and then switched to starter feed. As they mature, the young are transferred to adult feed, after which the fish can be moved to a common aquarium.

Diseases

Ornatuses have a strong immune system, which helps them to remain virtually disease-free. The fish are mainly susceptible to bacterial and parasitic infections and tolerate medications added to the water well. Diseases of this kind manifest themselves in the appearance of plaque on the body, frayed fins, lethargy, and cloudy eyes. The earlier treatment begins, the greater the chances of saving the fish's life.

Disease prevention consists of timely, complete, and competent aquarium care: cleaning the substrate and changing the water. Equipment, decor, and everything that goes into the aquarium must first be disinfected. Live food should only be purchased from reliable sources. Choose high-quality dry food. All new inhabitants must be quarantined before being introduced to the phantoms.

Ornatus are an excellent choice for aquarists who want to see not only bright colors in their underwater world, but also interesting, lively behavior. These small fish, especially in a school, can turn any aquarium into a dynamic and mesmerizing corner of nature.

Like any pets, they require attention to their living conditions. Clean water, stable parameters, and the right neighbors are the key to their health and long life. If you provide them with this simple care, ornate fish will delight you with their activity and grace for many years.

Overall, these fish prove that you don't have to be huge or exotically colorful to be interesting. Their charm lies in their agility, shoaling instinct, and the lively energy they bring to the aquarium. They remind us that the true beauty of the underwater world often lies in simple and harmonious things.
