The red ghost tetra fish (Hyphessobrycon sweglesi), also known as "fire tetras", are a gem for any aquarium hobbyist. These freshwater fish, belonging to the Characidae family, stand out for their striking color Red and their peaceful nature. Originating from South America, specifically the Orinoco River basin, they are an excellent choice for well-established community aquariums. Below, we will explore in detail the characteristics, care and requirements necessary to keep this species in optimal conditions.
Main characteristics of the red phantom tetra
El red phantom tetra It is a small fish that can reach a length of between 3 and 4 centimeters, although in some exceptional cases they can reach the 5 centimeters. Its body is laterally compressed, with a rounded abdomen and a coloration that varies from bright red to brown tones. This intense colour is accentuated by three characteristic black spots: two behind the opercula and one at the base of the dorsal fin.
Sexual dimorphism
Males can be distinguished from females by some notable differences. Males tend to have a more elongated dorsal fin and a more intense red, while in the females This fin is usually shorter and often bordered in white. Females also tend to have a more bulging belly, especially during the breeding season.
Life expectancy
Under proper conditions, the red phantom tetra can live between 3 and 5 years, although some specimens reach up to 6 years if they are provided with optimal care.
Natural habitat and distribution
El Hyphessobrycon sweglesi It is native to various rivers and tributaries of the Orinoco River basin, such as the Guaviare River, the Atabapo River and the Meta River. In their natural environment, these fish usually inhabit sewage, rich in vegetation and with little light. These waters are usually slightly acidic, with a pH of between 5.5 and 6.8, and a low hardness (3-10 dGH).
Requirements for the aquarium
To recreate the natural habitat of the red phantom tetra, it is essential to design a suitable aquarium that reproduces its original conditions.
Aquarium size
An aquarium with a minimum capacity of 1000g is recommended. 60-80 liters to maintain a group of at least 8-10 copies, as they are gregarious fish that need to live in schools to feel safe. A tank with dimensions of at least 80x30 cm It is ideal to provide them with enough space to swim.
water parameters
- Temperature: Between 22 ° C and 28 ° C, the ideal being between 24 ° C and 26 ° C.
- pH: Between 5.5 and 7.5, preferring slightly acidic values.
- Hardness: Soft to moderately hard water, between 3 and 10 dGH.
It is essential to perform regular water changes and maintain good filtration to prevent the accumulation of nitrogen compounds, since they are sensitive to poor water quality.
Aquarium decoration
The aquarium must be densely planted, especially at the edges, leaving open areas for swimming. Floating plants, such as salvinia or Java moss, are highly recommended, as they help to filter the light and recreate the shaded environment they prefer. dark substrate and the inclusion of roots or logs also contribute to increasing the feeling of security for the fish.
Automotive Lighting
They prefer one dim lighting, which can be achieved with low intensity lamps or by using floating plants that reduce direct light.
Meals
Red phantom tetras are omnivores and have a varied diet. They readily accept commercial foods in the form of flakes or granules, but it is advisable to supplement their diet with live or frozen foods, such as mosquito larvae, daphnia, brine shrimp and tubifex. A balanced diet not only ensures their health, but also intensifies their colouring.
Behavior and compatibility
The red ghost tetra is a fish peaceful and sociable, ideal for community aquariums. Although they are gregarious in nature, they can exhibit hierarchical behaviors between males, manifested in the form of fin displays and display movements. However, these interactions rarely result in fights.
Compatibility
They are compatible with other species de peces small and peaceful, such as other tetras (e.g. neon tetras or lemon tetras), rasboras, corydoras and small livebearers. However, they should not be kept with aggressive or much larger fish that may intimidate them or turn them into prey.
Reproduction
Breeding the Red Phantom Tetra in captivity can be challenging, but it is not impossible. To encourage spawning, it is necessary to condition a breeding tank with soft water, a pH of around 6.5 and a constant temperature of 27°C. Lighting should be dim, and it is advisable to include plants such as elodeas or Java moss to facilitate egg laying.
The female can deposit up to 250 eggs in a single laying, which will be fertilized by the male. It is important to remove the parents after spawning to prevent them from eating the eggs. fry hatch in about 2-3 days and can be initially fed with infusoria or liquid fry foods.
Common diseases
Although they are relatively hardy fishRed Phantom Tetra are susceptible to stress and common diseases such as white spot and bacterial infections if water conditions are not optimal. Maintaining good water quality and performing regular changes is key to preventing these conditions.
The Red Phantom Tetra is a fascinating species that brings color and life to any aquarium. Its maintenance is relatively simple if its basic requirements are respected, such as water quality, a suitable diet and an environment that imitates its natural habitat. In addition, its gregarious and peaceful behavior makes it an ideal choice for both beginners and experienced aquarists.
