About the Indian Glassy Fish – Species Summary

The Indian Glassy Fish, scientifically termed Parambassis ranga, is a remarkable species hailing from freshwater systems in parts of Southeast Asia. Noted for its almost transparent body, this fish offers a unique visual experience in an aquarium setting. Aquarists, especially beginners, appreciate the Indian Glassy Fish for its resilient nature, adaptability, and calm disposition. Nevertheless, a keen awareness of their habitat and dietary needs can ensure a thriving environment for these transparent wonders.

Indian Glassy Fish Care

Tank Size

For a school of Indian Glassy Fish, a 20-gallon tank serves as a good starting point. These fish thrive when in groups, and a spacious environment allows them to exhibit their natural schooling behavior.

How To Set Up Their Tank

While setting up their tank, aim for a setup that mimics their natural habitat. Subdued lighting, along with a mix of fine gravel and sandy substrate, works well. Adding live plants can provide shelter and help maintain water quality. Driftwood and rocks can further enhance the natural feel.

Lighting Requirements

Indian Glassy Fish prefer subdued lighting, which not only accentuates their transparency but also reduces stress, as bright lighting can be harsh on them.


A pH level ranging between 6.5 and 7.5 is ideal for the Indian Glassy Fish.


Consistency is key when it comes to temperature. A stable range between 72°F and 82°F (22°C to 28°C) should be maintained.

Water Parameters

Apart from the pH and temperature, the water should be soft to moderately hard. Regular water changes and maintenance are essential to keep nitrate levels low.

Disease Potential

Like all aquatic creatures, the Indian Glassy Fish is vulnerable to various diseases, most commonly Ich or White Spot Disease. Maintaining water quality, avoiding sudden changes in tank conditions, and quarantining new tank additions can mitigate these risks.

Food & Diet

Being omnivores, the Indian Glassy Fish’s diet includes both plant matter and small creatures. They usually thrive on high-quality flake food, supplemented with occasional live or frozen treats like brine shrimp, daphnia, or bloodworms.

Behavior and Temperament

Peaceful and schooling by nature, the Indian Glassy Fish are often seen moving in harmonious groups within the aquarium. They are generally non-aggressive, making them suitable for community tanks.

Tank Mates

Given their peaceful temperament, they cohabit well with other non-aggressive fish of similar size. Good tank mates include small tetras, rasboras, and gouramis. However, avoid housing them with larger or aggressive fish that might view them as prey.


Breeding the Indian Glassy Fish in captivity can be somewhat challenging but is feasible. They are egg scatterers, usually laying their eggs on broad-leaved plants. To facilitate breeding, provide a separate breeding tank with ample plants and maintain optimal water conditions. After spawning, it’s advisable to remove the adult fish to protect the eggs.
