Hyphessobrycon sweglesi is a species of tetra that lives in the Orinoco River drainage basin in South America.[2] The species' scientific name used to be Megalamphodus sweglisi and the species' common name is red phantom tetra.[3] It grows up to 4 cm (1.6 in).[4]

Appearance

The fish has a round black spot behind the gill-plate, a black band on the dorsal fin that is bordered above and below by creamy-white. The other fins are red same as the upper rim of the eye.[5] The species' appearance is very similar to Hyphessobrycon megalopterus (black phantom tetra).

In the aquarium

Water Conditions

Aquarists keep this fish in water ranging from 20 to 23 °C (68 to 73 °F) that is soft (50-100mg/L) and acidic (pH 6.5).[4] The H. sweglesi is reported to be very sensitive to water chemistry, which affects the fish's coloration.[4] Frequent water changes are advised for it to thrive and to induce it to breed.[4]

Diet

The fish eats worms, small insects, and crustaceans.[2] In captivity, aquarists feed it prepared foods and small live foods.[4]

Breeding

The species can lay up to 400 eggs that can hatch in a day. The eggs are susceptible to fungus.

Aquarists put dark substrate in the spawning tank to protect the eggs from light.[4]
