Reed Tetra (Hyphessobrycon elachys)

Reed Tetras are a peaceful species that shoal naturally in the wild. Therefore, they are happier, more vibrantly coloured, and more active when kept as a group of 8 or more individuals instead of singly.

Reed Tetras tend to be timid and should not be kept with large or aggressive fish who may bully or eat them because of their small size. Therefore, ideal tankmates for these Tetras would include other small and peaceful species such as small Tetras, Pencilfish, Dwarf Cichlids like Apistogramma or Mikrogeophagus, smaller Suckermouth Catfish and Corydoras Catfish.

The ideal aquarium for Reed Tetras should be furnished with plenty of driftwood to create plenty of shady areas. The driftwood will gradually release tannins into the water that will help acidify the water whilst giving it a natural, brown colour like their natural habitat. Adding peat filtration can also help in this respect. You should also add dense planting, both floating and rooted, which will help to make the fish feel secure. In addition, the lighting should not be too bright, and darker substrate and background choices will help show off these fish's stunning colours.

Reed Tetras have silver bodies and a broad anal fin lobe. These fish also have a combination of elongate dorsal and pelvic fins in mature males and a large prominent black spot on the caudal peduncle. You will also see white colouring on both sides of the black spot, and all other fins are translucent.

In the home aquarium, the Reed 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

Male and female Reed Tetras can be distinguished relatively easily. A mature male's dorsal and pelvic fin rays are elongated, and the anterior portion of the anal fin has a wide lobe shape. Additionally, males tend to be slightly larger and have brighter colours than females. Compared to their male counterparts, females tend to be smaller, more full-bodied, and duller.
