So, let’s dive deep into the world of these magnificent creatures and unravel the secrets to their optimal care.

Physical Characteristics

Size and Shape

They are one of the largest species of the cichlid family. They are also known as pterophyllum Altum, often reaching up to 13-15 inches in length. Their distinguishing feature is their elongated, triangular bodies, which coupled with their tall dorsal and anal fins, give them a unique, almost arrow-like appearance. This shape allows them to navigate swiftly through their native Amazon River habitats, darting among the dense vegetation with ease.

Unique Coloring and Vertical Stripes

The beauty of these fish lies not only in their size and shape but also in their unique colouring and striking vertical stripes. They exhibit a silver body overlayed with distinctive black vertical stripes that extend from the top of their dorsal fin to the bottom of their anal fin, creating a striking contrast. These stripes serve as a form of camouflage, helping them blend into their environment. Their body’s silver hue can shimmer with a hint of green or blue, especially under specific lighting conditions, making them a captivating sight to behold in any aquarium.

Natural Habitat

Native Amazon River Habitat

Altum Angelfish, true to their name, are native to the pristine, deep waters of the Amazon River, predominantly found in the Orinoco Basin. These waters are often characterized by a low pH, soft water conditions, and a high concentration of tannins due to the decomposing organic matter. The river’s environment is complex, filled with dense vegetation and a rich diversity of aquatic life, which offers these fish ample hiding spots and a variety of diet options.

Replicating Their Environment in Captivity

Replicating the natural habitat of these fish in an aquarium is essential for their well-being. This involves maintaining soft, acidic water conditions with a pH between 5.0 and 7.0. The tank should be well planted to mimic their natural surroundings, providing them with plenty of hiding spots. Additionally, as the Amazon River is relatively dark due to overhanging vegetation and tannins, it is also recommended to create a similar environment in the tank with subdued lighting. This helps in reducing stress and encouraging natural behaviour in these fascinating fish.

Tank Setup and Care

Suitable Tank Size and Water Parameters

Being one of the largest species in the cichlid family, requires a spacious tank to thrive. A minimum of 55 gallons is recommended, but a larger tank would be more suitable to accommodate their size and active swimming habits. The water temperature should be kept between 78-86°F (26-30°C), while the water hardness should be between 1-5 dGH. Remember, replicating the water conditions of their native Amazon River habitat is key to their health and longevity.

Providing Hiding Spots and Appropriate Tank Mates

Given their natural habitat’s complexity, providing plenty of hiding spots in the form of live plants, driftwood, and rocks is essential in a tank setup. When it comes to tank mates, they usually do well with other peaceful, similarly-sized fish. However, due to their semi-aggressive nature, it is advisable to avoid housing them with small, slow-moving fish that might be seen as prey.

Filtration and Water Quality Maintenance

Maintaining the water quality is crucial for the health of your fish. Implement a strong, effective filtration system that can handle the bioload and keep the water clean. Regular water changes, about 30-50% weekly, are also recommended to remove waste and prevent the buildup of harmful toxins. Monitoring the water parameters regularly will ensure a healthy and stress-free environment for these majestic creatures.

Feeding Habits

Dietary Preferences

They are omnivorous by nature and exhibit a diverse diet in their native Amazon River habitat. They primarily feed on small invertebrates, insects, larvae and plant matter. Their omnivorous diet is a testament to their adaptability, allowing them to exploit a wide range of food sources in their environment.

Feeding in Captivity

In captivity, They require a balanced diet to ensure their health and vitality. High-quality flakes or pellets form the basic diet, but their meals should be supplemented with live or frozen foods like bloodworms, brine shrimp, and daphnia. Plant-based foods, such as spirulina and blanched vegetables, also contribute to their nutritional needs.

Feeding Schedule and Quantities

A regular feeding schedule is recommended for this fish. Feed them small, manageable amounts 2-3 times a day, making sure to remove any uneaten food to maintain the water quality. Overfeeding, apart from polluting the water, could also lead to health problems like bloating or obesity in these fish. Therefore, moderation is crucial while feeding them.

Adapting to Food Changes

They can often be picky eaters, especially when introduced to new types of food. However, they usually adapt over time. If you’re introducing a new food to their diet, do it gradually and ensure it’s done along with their regular food until they get used to it.

Breeding Altum Angelfish

Breeding Conditions and Process

Breeding these fish is quite a challenge, as they have specific conditions that must be met for successful spawning. The water parameters should match those of their natural Amazon River habitat, with the pH remaining on the acidic side. The tank should be spacious, mimicking their wild environment with ample hiding spots. It is also beneficial to condition the potential breeding pair with a nutritious diet to encourage spawning.

Breeding Behavior and Egg Care

During breeding, one can observe fascinating behaviours. The pair will choose a flat surface, like a broad leaf or a piece of slate, where the female will lay the eggs and the male will fertilize them. Once the eggs have been laid, both parents exhibit protective behaviours, often guarding the eggs against potential threats.

Fry Care

After hatching, the fry is relatively small and requires special care. Initially, they feed off their yolk sac, but once depleted, they should be fed with a diet of infusoria or freshly hatched brine shrimp. As they grow, the diet can gradually be expanded to include larger food items. Regular water changes are vital during this stage to maintain high water quality, ensuring optimal growth and health for the fry.

Common Health Issues

Recognizing Symptoms

Just like any other aquatic species, these are susceptible to various health issues. It’s crucial for aquarists to be able to identify signs of illness early on. Symptoms can include unusual behaviour such as lethargy or loss of appetite, changes in colouration, or physical abnormalities like spots or lesions on the skin.

Common Diseases

Several diseases commonly affect these fish. Ich, a parasitic infestation, often manifests as white spots on the fish’s body. Another common ailment is fin rot, characterized by fraying or discolouration of the fins. Swim bladder disease, which affects the fish’s buoyancy, is also observed in some cases.

Preventive Measures and Treatments

Maintaining optimal water conditions is the first step in disease prevention. Stress, often caused by poor water quality or improper tank conditions, can make these fish more susceptible to disease. Regular water changes and monitoring of water parameters are crucial for prevention. In case of disease, various treatments are available depending on the specific illness, including medication, salt baths, and quarantine procedures.

Regular Health Checkups

Consistent observation of the fish’s behaviour and physical condition can help detect any health issues at an early stage, allowing for prompt treatment. This, combined with regular preventive measures, can ensure a long, healthy life for these majestic freshwater creatures.
