Indian Glass Fish – Parambassis ranga

Indian Glass Fish, scientifically known as Parambassis ranga, is a fascinating species renowned for its almost completely transparent body, allowing you to see its internal bones and organs. Native to South and Southeast Asia, including India, Bangladesh, and Thailand, this fish is a popular choice for aquarists looking for something truly unique.

In its natural form, the Indian Glass Fish has a clear, glass-like appearance with a slight silver sheen, sometimes reflecting subtle hints of yellow or green under lighting. Unfortunately, artificially dyed variants are sometimes sold in the trade—these should be avoided as they are less healthy. Always choose natural, non-dyed specimens for better longevity and ethical fishkeeping.

This species thrives in peaceful community aquariums, especially when kept in groups. Their semi-transparent bodies create a stunning visual effect, particularly in planted tanks where light and movement highlight their delicate structure.
