Lala Glassfish

Adults of this species reach approximately 4 cm in length. The fish's body has a rhomboid shape, with distinctive features being a large head and pointed fins. The translucent body coverings are a characteristic feature of the Lala Glassfish, through which its spine, ribs, and internal abdominal organs are clearly visible. Males are distinguished from females by the presence of a bluish edging on their fins.

These fish are popular in Asian countries, but they are supplied not in their natural coloration, but with various patterns, bright designs, or in unusual saturated colors such as red, yellow, green, and others. Such coloration is created artificially using dye injections. Thus, local breeders aim to make them more attractive to buyers. In European and American countries, the practice of dyeing fish is prohibited by law, so only fish in their natural state, without Asian modifications, are available for sale.

The Lala Glassfish inhabits freshwater bodies in South Asia, including India, Bangladesh, and Myanmar. In nature, it lives in stagnant or slow-moving waters: ponds, ditches, and vegetated areas of rivers. The species prefers densely planted areas where it stays in schools in the water column.

Distinguished by their peaceful nature, these fish live in large schools in their natural habitat. For aquarium keeping, it is recommended to acquire a group of 8–10 individuals or more. They coexist perfectly with other species of similar size and temperament.

For a small school of Lala Glassfish, the optimal aquarium volume starts from 40 liters. The aquarium setup can be arbitrary but must include areas with dense plant thickets. The only thing that might cause difficulties is their feeding. These fish feed exclusively on live or frozen foods; they usually ignore dry foods. They prefer soft, slightly acidic water. Regular aquarium maintenance combined with uninterrupted filtration will help maintain the necessary hydrochemical composition of the water and prevent the accumulation of organic waste.

In its natural environment, it is a predator, feeding on small invertebrates. In aquarium conditions, it is extremely important to use live or high-quality frozen foods, such as daphnia, artemia, or small bloodworms. Dry commercial foods are usually ignored by the fish, so their use as a primary diet is not recommended.

Spawning is paired and occurs among fine-leaved plants, where the female lays her eggs. The fish do not show pronounced parental care. Breeding is considered difficult due to specific requirements for initial food: the larvae are extremely small and require microscopic live organisms, such as nauplii of certain copepod species, for successful rearing.

The species is sensitive to water quality and stress factors, which often provoke the development of bacterial infections and parasitic diseases. Common symptoms include:

• appearance of whitish coatings or spots on the body
• fin rot
• rapid breathing
• refusal to eat and apathy

Prevention involves maintaining stable environmental parameters and regular water changes.

When purchasing, avoid individuals with signs of emaciation, fin damage, or unnatural behavior. It is crucial to refrain from acquiring fish with artificially injected fluorescent dyes, as this procedure causes serious harm to their health and significantly shortens their lifespan. A healthy fish should be active, have clear eyes, and characteristic body transparency.
