Habitat

Black phantom tetras are very popular in fishkeeping due to their red eyes, black body, and long elegant fins. They are schooling fish, meaning they will live happily if kept in groups of at least 5 or more.

Keeping them in a community aquarium is ideal, as they will get along with other small, peaceful species such as danios and rasboras, even some algae eaters like dwarf corydoras. They should not be kept with fast-moving or aggressive species that might harass them.

Black phantom tetra size

When fully grown, black phantom tetras measure about 3 inches. Males can be slightly larger than females, but not much.

Black phantom tetra tank size

The minimum recommended tank size is 10 gallons (38 liters); 20 gallons (76 liters) or larger is ideal. Tetras are shoaling fish, so an aquarium with multiple compartments will be needed to house a group of 5 or more.

Black phantom tetra tank mates

This fish is a great community aquarium fish and can be kept with most other similar-sized tetras, rasboras, barbs, and danios. They are okay with live plants but not an absolute necessity for them to be healthy. Because they are relatively small (up to 3 inches) you should avoid housing them with much larger tropical or cold water fish who may see them as food.

Some good tankmates are Cardinal tetras, rummy nose tetras, black neon tetras, harlequin rasboras, and other smaller barbs and danios.

Some good plants for the tank are hornwort, Amazon frogbit, duckweed, java moss, and water wisteria.

The Black Phantom Tetra is a livebearer and is usually bred in pairs or groups. They can have up to 2,000 fries per batch. The eggs are transparent and become opaque after fertilization and should be removed as soon as they are noticed. Ideally, you want them to hatch within 24 hours at 75°F (23°C). Eggs will develop faster if there is more than one male for every female.

Are black phantom tetras aggressive or peaceful?
