Kogal Blue Eyed Tetra (Moenkhausia sp)

Kogal Blue Eyed Tetras are peaceful and active shoaling fish that visually improve as they mature. These fish can tolerate harder water conditions but should only be kept in soft to medium water conditions over a long period.

Kogal Blue Eyed Tetras are shoaling fish in nature; therefore, you should keep these fish in a group of at least six individuals. If you maintain these Tetras in decent numbers, any altercations are generally contained within the group. However, like most Tetras, this species fares better in the presence of their own kind and are usually a little skittish if you keep them in insufficient numbers.

Kogal Blue Eyed Tetras are best kept in an aquarium with plenty of aquatic plants, open swimming spaces, as well as subdued lighting or shade. Using a dark substrate would also be beneficial as this would show off their beautiful colours.

Due to their relatively high activity level, these Tetras are best kept with other active tankmates. In addition to Tetras and Barbs, larger Rasboras, Rainbowfish, and many Danios are excellent choices. Aside from these, bottom dwellers such as the Corydoras Catfish and Loaches are also good companions. It is also possible to use these Tetras as a dither fish for medium-sized, non-aggressive Cichlids.

The Kogal Blue Eyed Tetras have golden iridescent bodies and a dark line horizontally crossing their bright blue eyes. These fish also display an elongated horizontal blotch on their caudal peduncle.

In the home aquarium, the Kogal Blue Eyed 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 quite challenging to differentiate between the males and female Kogal Blue Eyed Tetras. The only genuinely distinguishing feature is that the females have more rounded bodies than males when ready to breed.
