Highfin Glassy Perchlet - Parambassis lala : Complete Fish Profile & Care Guide

Table of contents


Highfin Glassy Perchlets (Parambassis lala) constitute a robust and distinctive addition to small to medium-sized tranquil community aquariums, characterized by their translucent appearance and schooling proclivity. In an aquarium setting, these fish thrive when maintained in groups of five or more, ideally cohabiting with congenial tankmates such as Barbs, Livebearers, smaller Rainbowfish, select Tetras and Loaches.

To establish an optimal habitat for these moderately sized and active swimmers, it is imperative to provide ample space, abundant aquatic vegetation, robust filtration systems, and areas with pronounced water currents to emulate their natural habitat. Maintaining a high level of water oxygenation is of paramount importance. Decorative elements such as driftwood and polished stones, ranging from boulders to cobbles and pebbles, can be strategically arranged to create pockets of relatively calmer water, simulating their native environment.

Males of the Highfin Glassy Perchlet exhibit a striking whitish-blue seam along their anal and dorsal fins, a distinctive feature absent in females. Both sexes display transparent bodies with a subtle yellow-gold hue and prominent dark vertical bands, facilitating their identification and distinguishing them from closely related species that may occasionally infiltrate the aquarium trade.

Natural Habitat

Highfin Glassy Perchlets, recognized as a widely distributed species, have been documented in regions spanning India and Myanmar. Specifically, their presence is well-documented in the lowlands of the Ganges-Brahmaputra and Mahanadi Basins in India, as well as the Irrawaddy Basin in Myanmar, with a notable concentration in Assam.

Within their natural habitat, this species consistently occupies expansive watercourses characterized by exceptional water clarity and high oxygen levels. These habitats are often in close proximity to turbulent rapids and substantial riffles, with substrates predominantly comprised of smooth rock formations and an array of boulders, thus contributing to the distinct aquatic environment that defines this species.

Contrary to some outdated information, it is imperative to note that the Highfin Glassy Perchlets predominantly inhabit pure freshwater environments and do not demonstrate a preference for or necessity for brackish conditions. Such nuanced insights contribute to a more comprehensive understanding of their ecological requirements.


Similar to their counterparts within the Glassfish family, successful captive breeding of Highfin Glassy Perchlets remains an unachieved endeavour in the context of home aquariums. Their breeding behaviour involves the scattering of eggs, indicative of a reproductive process that is expected to mirror a comparable pattern in captivity.

Diet & feeding

Highfin Glassy Perchlets have a carnivorous diet that closely mirrors their natural feeding habits in the wild. These fish primarily feed on a variety of small aquatic organisms. In their diet, live foods such as brine shrimp, Daphnia, and tiny aquatic insects take precedence, offering essential nutrients and replicating their native prey. Additionally, frozen foods like bloodworms, tubifex worms, and mosquito larvae are commonly provided in aquarium settings, providing a convenient and nutritious source of sustenance. 

High-quality fish pellets and flakes designed for carnivorous species also constitute a significant portion of their diet, typically enriched with essential proteins. Occasionally, small live or frozen fish and crustaceans may be introduced to their menu, ensuring a diversified and well-balanced diet for these captivating and delicate aquarium inhabitants. Maintaining a proper diet is crucial to their overall health and vitality.
