Indian Glass Fish (Parambassis ranga)

Indian Glass Fish have been relatively popular in the aquarium for many years. They have a reputation for being fragile and difficult to keep. However, they are very tolerant of water parameters. Indian Glass Fish are peaceful and shy; you should not house them with robust or aggressive species.

Indian Glass Fish are shoaling species and will not do well if you keep them alone or in pairs. Therefore, it would be best if you kept them in groups of 6 or more individuals.

Indian Glassfish have deep bodies and are laterally compressed. Their fins are long and rounded except for two separate, pointed dorsal fins.

Their caudal fin is relatively long and forked, their back is arched, and their mouth is small and dorsally located. Their Forehead is slightly indented, and their eyes are rather large. These fish have a remarkably silvery transparent body with a pale amber to green iridescence, revealing their bones and internal organs.

Indian glassy fish have often been sold to hobbyists after being painted, injecting coloured dye within the fish's transparent tissue to make them more appealing to hobbyists. These colours are usually fluorescent yellow, pink or green.

Unaccustomed fishkeepers are often fooled into believing such fish are natural or that the process causes no harm and is painless. However, this is not the case. Instead, these fish have suffered trauma, becoming susceptible to fin rot, lymphocystis, and velvet disease.

What makes this worse is that artificial colouration is only temporary and often fades quickly. So dyed fish of this and other species are still available in numerous countries. Fortunately, protracted campaigning has seen them banned from UK stores.

In the home aquarium, the Indian Glass Fish will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

2 interesting tank mate ideas for the Indian Glass Fish could include:

Banded Gourami(Trichogaster fasciata)
Indian Hifin Barb(Oreichthys cosuatis)

Sexual Dimorphism

It is simple to distinguish male from female Indian Glass Fish. The males develop a dark blue edging on the anal and dorsal fins and have a slightly deeper yellow on the body than females. These differences are more visible when the fish are procreating, as the colours become more intense. The visible swim bladder has a pointed back edge in males.
