Steel Blue Tetra (Hyphessobrycon weitzmanorum)

Blue Steel Tetras are peaceful and undemanding and will acclimate to various water conditions. However, very hard water may prevent these Tetras from reaching their full potential in colour.

Like many other Tetras, planted aquariums with darker substrates or subdued areas will provide the best home for your fish and will result in more vibrant colours and improved health. However, even though they are peaceful, these Tetras may nip the fins of long-finned species such as guppies or Siamese Fighting Fish, especially if the Tetras are kept in smaller numbers.

It would be best if you maintained Steel Blue Tetras in a group of 5 or more individuals. Not only will they fare much better when in the company of their own kind, but it will also result in a far more effective, natural-looking shoal and make your fish feel more secure. In addition, you may also see some fascinating displays of fin flaring by rival males if several are present.

Ideal tankmates for your Steel Blue Tetras would be other small and peaceful species such as Hatchetfish, Loaches, Corydoras Catfish, Rasboras, small to medium-sized Barbs, Dwarf Gouramis and West African Dwarf Cichlids. In addition, because of their shape, you can also keep these Tetras with larger Cichlids such as Discus and Angelfish. Unfortunately, Steel Blue Tetras can be easily intimidated, so make sure you do not house them with much larger boisterous species.

Steel Blue Tetras have a darkish blue to almost black body colour. This is because they have a high concentration of dark chromatophores evenly distributed over the lateral surfaces of the body. In addition, these Tetras display two vertically elongated humeral spots, including somewhat rounded margins. These Tetras also have orange colouration on their anal, caudal, pelvic and dorsal fins.

Feeding

In the home aquarium, the Steel Blue 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 simple to distinguish between the male and female Steel Blue Tetras. Males will typically develop extended anal and dorsal fins as they grow and are usually larger, slimmer and more colourful than females. In contrast, the females have shorter fins, and their bodies are generally rounder, especially when spawning.
