Glowlight Rasbora (Trigonostigma hengeli)

The glowlight Rasbora is very small but is surprisingly eye-catching in appearance. These Rasboras are an excellent fish for the beginner aquarist who wants something special for a peaceful community tank.

Even more exciting than their looks is their engaging, fast-paced lifestyle, they are a charm to watch. It would be best if you maintained these fish in a school of at least eight individuals as the company of their own species is essential to their well-being. You can house these Rasboras in a nano tank or a planted aquarium.

Their colour ranges from translucent ivory to a pink-blushed orange. Their fins are a sharp lemon yellow and the most distinguishing feature is a brilliant strip of neon orange just above a thin black marking along the back half of their body.

In the home aquarium, the Glowlight Rasbora 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.
