Glass Catfish (Kryptopterus vitreolus)

Glass Catfish is a freshwater ray-finned fish of the catfish family. They get their name from their translucent body that lets you see their organs and bones.

Unlike other typical catfish that you see sucking on rocks, tank sides and feeding on the bottom, this species although they do have barbels have chosen the free-swimming lifestyle instead.

The Glass catfish is a very peaceful and timid fish that keeps to themselves, only going for cover when disturbed, therefore, making a great addition to a community tank.

In the home aquarium, the Glass Catfish 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.

Sexual Dimorphism

Unfortunately, there is no possible way to differentiate a male from a female.
