Species description

Care, breeding and tankmates

Fish profile

Temperament

Semi-aggressive

Their temperament is peaceful, making them ideal community residents. They might initially hide when introduced to a new tank. Eventually, they display a curious and lively disposition.

Diet

Carnivore

They naturally consume small invertebrates and zooplankton from the water surface. High-quality dry foods are eagerly accepted in the home aquarium. Offering bloodworms or daphnia occasionally ensures balanced nutrition and health.

Sex ratio

Harem

A harem setup of one male per multiple females is advised. This arrangement minimizes stress and territorial disputes among males. Dense planting provides necessary refuge for the females.

Feeding frequency

Twice daily

It is recommended to offer them food twice a day. Provide only what they can consume in under three minutes. Overfeeding should be avoided to maintain pristine water conditions.

Bioload

Pyrrhulina laeta generates a very small bioload due to its modest size. Aquarium water quality remains stable easily with regular partial water changes. A standard hang-on-back or sponge filter is perfectly adequate for their waste.

Flow

Stagnant

Gentle water movement replicates their native slow-moving streams. High flow rates can cause them undue stress and fatigue. Utilizing spray bars can effectively distribute the return flow.

Reproduction

Oviparous

Spawning occurs when females deposit eggs on broad plant leaves. Males take on the responsibility of guarding the eggs fiercely. Hatching occurs within a few days under optimal warm conditions.

Compatibility & tankmates

This species is highly compatible with other peaceful nano fish. Corydoras and small rasboras are excellent choices for tank mates. Fin-nippers and large cichlids should be strictly avoided.

Tank level

Top

They are classic top-to-middle water column dwellers. They spend most of their time patrolling just beneath the surface. Sinking foods are often ignored unless they are very hungry.
