Species description

Care, breeding and tankmates

Fish profile

Temperament

Semi-aggressive

It is an active and generally peaceful species, although males can exhibit some territoriality toward each other or during the breeding phase. They should be kept in groups of at least six individuals to encourage natural and balanced social behavior. Their vivacity and elegance make them a dynamic presence in the middle and upper layers of the tank.

Diet

Omnivore

It is an omnivorous micro-predator that prefers animal-based foods but accepts a wide range of products. In the aquarium, it particularly appreciates small insects, larvae, live or frozen mysis and brine shrimp, alongside high-quality flake or granular foods that remain on the surface or sink slowly. A varied diet contributes to enhancing the beautiful red spotting on the males' flanks.

Sex ratio

Harem

When keeping the red-spotted copeina, it is highly recommended to maintain a harem ratio of one male to several females. Males can be territorial and display aggressive behavior towards competing males, especially during the breeding season. Providing multiple females diffuses the male's attention and reduces the stress placed on any single female. If the aquarium is sufficiently large and densely planted, multiple males can be kept together, provided the female ratio remains high.

Feeding frequency

Twice daily

It is recommended to feed them once or twice daily, providing controlled portions that are entirely consumed within two minutes. Since they feed primarily in the upper water layers, food should be introduced gradually to prevent it from settling unused on the bottom. Occasional one-day fasting periods can benefit their digestive system.

Bioload

The red-spotted copeina produces a relatively low bioload, making them very manageable for standard aquarium filtration systems. They are small, slender fish that consume appropriately tiny portions of micro-pellets, flakes, and live foods. Provided they are not chronically overfed, a typical sponge filter or small hang-on-back filter will easily process their biological waste. Routine partial water changes are generally sufficient to maintain the pristine water conditions they prefer.

Flow

Stagnant

They prefer a weak to moderate water flow, simulating the calm waters of secondary rivers and swampy areas of the Amazon. Too strong currents can constantly fatigue them and limit their natural swimming behavior near the surface. It is advisable to position natural barriers like floating plants or driftwood to create areas of absolute calm.

Reproduction

Oviparous

They display a highly interesting breeding behavior that differs from other species in the genus. The male digs a small depression in the sandy substrate where the female lays the eggs, which are then fertilized. Subsequently, the male assumes full responsibility for the clutch, guarding the nest and fanning the eggs with his fins until they hatch, which occurs in about 30 to 48 hours.

Compatibility & tankmates

They are excellent fish for community aquariums, provided that the tankmates are of similar size and peaceful. They associate well with other medium-sized characins, armored catfish (Corydoras), and tolerant dwarf cichlids. Avoid extremely small or timid fish that could suffer from the males' vivacity during the breeding season.
