Dawn Tetra (Aphyocharax paraguayensis)

The Dawn Tetra is a hardy and undemanding, very active fish and remarkably aggressive towards fish that are slower moving, similar in size or smaller; therefore, they are not suitable for the community tank. However, the more significant the group, the less aggressive they become

The Dawn Tetra has a torpedo-shaped silver body with opalescent pale green reflecting from the scales behind the gill plates along the central, lateral area to the root of the caudal fin.

This fish is unique as it has a moderately full, black line running along the line of the spine from the back of the gills to its caudal fin and then continuing along the lower caudal fin to its tip.

Most of the fins are transparent. The anal fin has a strong, black band closest to the body before becoming transparent. The caudal peduncle is black and extends into the caudal fin about one-third of the way to the back of the tail. Below and above this black section of the caudal fin have white patches which extend, again, about one third the length of the caudal fin. The rest of the caudal fin is transparent.

Feeding

In the home aquarium, the Dawn 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.

Sexual Dimorphism

It is relatively easy to determine males from females. The male has more distinctive, bolder markings and a more decisive marking on the anal fin whereas, the females are slightly fuller-bodied than the males.
