Penguin Tetra (Thayeria boehlkei)
The Penguin Tetra is a peaceful, hardy and adaptable fish. They can be sensitive to nitrates but apart from that are relatively easy to care for and are ideal for beginners, and they make a lovely addition to an aquarium. This species does best in a densely planted aquarium.
The Penguin Tetra is usually olive with a prominent black line running down the lateral into the lower half of the tail fin, and its belly is silver colour. This species unusual swimming/resting motions can be quite eye-catching, and give the fish a strong sense of individuality amongst similar sized tank mates.

In the home aquarium, the Penguin 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.
