General Description
Pethia reval, formerly known as Puntius reval, is a small cyprinid species endemic to western Sri Lanka. It can be distinguished from its closely related species by its red fin coloration, smaller eye diameter, and unique body markings. This peaceful fish is best kept in schools of 6-10 individuals to reduce skittish behavior and enhance coloration.
Aquarium Setup
In aquariums, Pethia reval thrives in a well-planted environment with a dark substrate, benefiting from the presence of floating plants and driftwood. Water conditions should be maintained within a pH range of 6.0-7.5, a temperature of 18-26°C, and a hardness of 36-215 ppm (see table). Moderate water movement and hill stream-like setups are appreciated by this species.
Behaviour
Known for its peaceful nature, Pethia reval is an excellent community tank inhabitant that can coexist with various fish species including small cyprinids, tetras, livebearers, rainbowfishes, and catfish. Maintaining them in schools helps reduce skittish behavior and enhances the coloration of males due to intra-species competition.
Feeding and Diet
In the wild, Pethia reval feeds on diatoms, algae, small insects, worms, and zooplankton. In captivity, they readily accept a diet of small live and frozen foods like bloodworms, Daphnia, and Artemia, supplemented with high-quality flakes and granules containing plant and algal matter.
Reproduction & Dimorphism
Details on the reproduction of Pethia reval are currently unrecorded. Adult males of this species are slimmer, smaller, and more vibrantly colored than females, especially during the breeding phase. This dimorphism is particularly prominent when males are in spawning condition.
Habitat and Distribution
Natively found in the Kelani and Maha Oya river systems of Sri Lanka, *Pethia reval also inhabits smaller drainages like the Attanagalu and Kalu rivers within its range. The fish may potentially hybridize with P. cumingii in the southern part of its distribution, while populations introduced artificially exist in the Mahaweli River.
