Species description

Care, breeding and tankmates

Fish profile

Temperament

Semi-aggressive

They have a very shy and peaceful temperament. They rely heavily on the security of their school and the presence of hiding spots. They are charming but require a dedicated setup to truly thrive.

Diet

Omnivore

They are micro-predators that require very small-sized foods. Crushed flakes and specialized micro-pellets are accepted but should not be the only food. Live or frozen baby brine shrimp and daphnia are critical for their long-term health and vibrant color.

Sex ratio

Group

Keeping them in a group of at least eight to ten individuals is crucial. A mix of males and females encourages natural behaviors and vibrant displays from the males. Females are generally rounder and slightly less colorful.

Feeding frequency

Twice daily

Feed them tiny amounts two to three times a day. Their small digestive tracts process food rapidly. Ensure the food particles are small enough for their tiny mouths to ingest easily.

Bioload

The Fire Rasbora produces a very small bioload due to its tiny size. They are highly sensitive to water parameter fluctuations and poor water quality. Excellent biological filtration and frequent small water changes are absolutely necessary.

Flow

Stagnant

They originate from sluggish forest streams and strongly prefer gentle water flow. Excessive current will quickly exhaust them and cause stress. Sponge filters or heavily baffled canister outputs are highly recommended.

Reproduction

Oviparous

Breeding is challenging and requires very soft, acidic water and dim lighting. They are egg-scatterers that will consume their own eggs if left in the breeding tank. The fry are microscopic and require infusoria as their first food.

Compatibility & tankmates

They are timid and extremely peaceful, suitable only for very tranquil setups. Tiny rasboras, dwarf corydoras, and small shrimp make ideal tank mates. Fast-moving or large fish will outcompete them for food and cause severe stress.

Tank level

Middle

They prefer to inhabit the middle to lower levels of the aquarium. They appreciate dense planting and shaded areas to retreat to. They rarely swim in the completely open upper water column.
