Overview
The teardrop rasbora is a small, peaceful schooling fish for a soft-water community tank. It is best kept by someone with a little experience.
Did you know
The teardrop rasbora was named for a single teardrop-shaped mark at the root of its tail, where its faint side stripe ends. That mark is one of the more wistful features ever chosen to define a species.
Caring for the teardrop rasbora
Keep teardrop rasboras in a group of at least eight, in a tank of 14 gal (54 L) or more. A planted, shaded tank with soft, tannin-tinted water keeps a group settled and colored up. They show best over a dark substrate, with leaf litter and gentle filtration.
Keep the water at 73 to 81°F (23 to 27°C) and a pH of 5.5 to 7.0. Aim for the softer, more acidic end of that range for the best color. Feed small foods, from fine flake and crushed pellet to frozen and live daphnia, cyclops and microworm.
Teardrop rasboras are peaceful and hold the middle of the tank. They suit a calm community of other small Bornean or blackwater species, gentle dwarf gouramis and quiet bottom-dwellers. Breeding them at home is not documented.
Good to know
The teardrop rasbora, Rasbora lacrimula, was described in 2009 and belongs to the family Danionidae. Its species name means little tear. It also carries tiny tubercles that form a rough crest along the back, which helps separate it from similar rasboras.
In the wild
The teardrop rasbora is known from the upper Mahakam drainage in Kalimantan Timur, Indonesian Borneo. It lives in small forest streams with soft, acidic, tannin-stained water.
