American Cichlid – Red Tiger Oscar Medium – 7cm

Red Tiger Oscar Medium: Bold and Vibrant Aquarium Addition

The Red Tiger Oscar Medium (Astronotus ocellatus) showcases the striking red and black tiger-like patterns that make this species so popular. Known for its intelligence and engaging behaviour, this medium-sized cichlid is perfect for aquarists looking to add personality and bold colours to their aquarium.

Tank Setup for Red Tiger Oscar Medium

A tank of at least 300 liters is recommended to house a medium-sized Red Tiger Oscar comfortably. These active fish need open swimming spaces along with sturdy decor like driftwood, rocks, and robust plants to create a natural environment. Maintain water temperatures between 24°C and 28°C, with a pH of 6.5 to 7.5. A powerful filtration system is essential to handle their high waste production and keep the water pristine.

Feeding and Nutrition

Red Tiger Oscars thrive on a varied diet. High-quality cichlid pellets should form the base of their nutrition, complemented by live or frozen foods such as bloodworms, shrimp, or crickets. Occasionally, offer vegetables like peas or zucchini to support their overall health. A well-rounded diet enhances their vibrant colours and keeps them active and healthy.

Behaviour and Tank Mates

Although medium in size, Red Tiger Oscars are still territorial and require careful selection of tank mates. They pair well with similarly sized, robust fish like silver dollars, plecos, or other large cichlids. Avoid smaller or more delicate species, as Oscars may see them as food. Providing ample space and hiding spots can reduce territorial disputes and promote harmony.

Growth and Breeding Potential

While currently medium-sized, these Oscars can grow up to 35 cm as adults. With the right care, they may become breeding candidates. Breeding requires stable water conditions and flat surfaces like rocks for spawning. Oscars are excellent parents, guarding their eggs and fry diligently. Feeding fry baby brine shrimp or finely crushed flakes ensures healthy growth.
