Fighting fish male superdelta koi - Betta splendens

Koi fighting fish are real eye candy and great representatives of the high breeding fraction. They are representative of the koi in the pond and feature, among other things, their great colors and patterns. Especially intensive breeding efforts and strict selection have made these animals what they are today: excitingly attractive color catchers in the aquarium!

The Superdelta fighting fish male offered here has the great Koi pattern, which may differ slightly from the photo, as all animals have their own personal pattern. The Superdelta convinces by its special fin shape.

Fighting fish once came from South-East Asia and are found in rather stagnant and quite low-oxygen waters, which are also located in flooded areas. In their countries of origin, they are sometimes still bred for exhibition fights with other fish, and in the past they have sometimes fought for home and court. Their breeding has a long tradition in Asia.

Although male fighting fish are strict loners, the females can be kept in groups of the same sex. They can also become loyal and tame family fish if you spend a little time with them. Male fighting fish can be distinguished from females by their imposing fins. These can grow up to three times as large as those of the females. Even though females develop a so-called genital papilla, this is not always a sexual characteristic.

You can also breed these foam nest builders quite easily. The most common method is probably to keep the selected breeding pair separate from each other and "get them in the mood" with large amounts of live and frozen food. The water temperature may be increased up to 28 °C for this purpose. The stimulated male starts to build a foam nest on the water surface with the help of water plants.

By far, the fighting fish is the only known aquarium fish that can be kept alone in an aquarium without technology. Aquariums without technology require special attention and sometimes need to be maintained more intensively than filtered aquariums. Concerning its water values the fighting fish is very tolerant and can be maintained in almost all hardnesses, if it was acclimated properly and the water temperature is at least 26° C. In the community aquarium the fighting fish claims its own territory of 40-50 cm on average, which it regularly swims off and "defends" - mainly threatening with raised gill covers, but will not seriously attack any fellow fish. However, since this costs him a lot of energy, he will probably live shorter.

KaFis like dense weed cover, especially in the middle to upper water zone, on which they also rest at times. These intelligent animals observe a lot and can even recognize their keepers. After a short time they even eat food from tweezers and are also capable of jumping, among other reasons therefore the aquarium should be covered. In their habitat, the fish sometimes jump between puddles and open water during mating season. Since the fish breathes at the surface of the water, this air should be warmed, otherwise it can get an inflammation of the labyrinth organ - here, too, the cover offers advantages.

Fighting fish feeds on approaching insects and tiny crustaceans, so it can be kept conditionally with well-reproducing dwarf shrimp, but it may eat their offspring. An alternative could be Amano shr imps, but it is possible that he will nibble on them, although he will not get them into his mouth. Dwarf crayfish can pinch the long and soft fins of the KaFi sensitively, which is why they are just as unsuitable as crayfish for socialization. A species tank would be advantageous. In a community aquarium it can be socialized with not too hectic and not fin-nibbling fish like tetras, barbs and loricariids . Long-finned fish are sometimes perceived as competition by male bettas and also cause great stress.

As a carnivore, the fighting fish can be fed a fairly varied diet of fine soft granules for bettas, but also excellent live and frozen foods such as white, red and black mosquito larvae, grindalworms, artemia, daphnia and enchytraea.

Our food recommendation: With the NatureHolic BettaFeed a special food for fighting fish has been tailor-made, whose soft soft granules resemble the consistency of insect larvae in nature. The soft beads protect the sensitive fish mouth from micro-cracks caused by too hard food grains. The specially developed NH Immun+ complex as well as the NH Color+ high-performance additive support the immune system and the magnificent color formation of the fish.

Our plant recommendation: Use for planting NatureHolic InVitros. These are free from snails, planaria and other unwanted co-inhabitants. Also free of algae spores, bacteria and fungi.

Expert Tip: We recommend when keeping fish the NatureHolic 3 Phase Liquid. The care set offers the best all-round protection for your animals. It ensures optimal conditions for successful breeding and keeping.
