Glowlight Tetra (Hemigrammus erythrozonus)

The Glowlight Tetra is a small and slender, attractive, peaceful, shoaling fish. Its friendly and active disposition and ease of care make it an ideal and famous fish for the community aquarium. It should be kept with similar-sized, non-aggressive species.

This Tetra is silver in colour and has a bright iridescent orangey-red stripe that continues from the snout to the base of its tail; the front of the dorsal fin is the same colour as the stripe. The anal and pelvic fins are transparent and edged in white.

Feeding

In the home aquarium, the Glowlight Tetra 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.
