Betta krataios



Betta krataios or cockerel kratajos live in the wild in forest marshes and streams that are sometimes not more than a few centimetres deep on the island of Borneo, Indonesia. The fish can be found in the shade of the trees, where the sun's rays hardly reach and half-light reigns. The water itself has a brownish colouring due to the humic acids released during the decomposition of organics at the bottom. The substrate in these areas consists mainly of fallen tree leaves, branches and snags. Overall, the fish are unsightly and unpopular with aquarists.

The fish's colouring is dark grey with a turquoise tinge. Betta krataios males are larger than females, their head is wider with an iridescent sheen, and their fins are elongated. The size of the fish is 4 to 4.5 cm.

Keep Betta krataios preferably in a species aquarium or in a general aquarium with peaceful, calm fish. Cockerels kratajos lead a quiet, measured life and if the aquarium with them will live overly active fish, the latter will constantly bully to cockerels, resulting in them constantly be forced to hide in hiding. This leads to the risk that the fish will be chased away from the feeding area and as a result they will starve.

The fish may be kept in a fully equipped aquarium or without substrate. The aquarium is then much easier to look after. However, a leaf mat consisting of dried beech or oak leaves should preferably be kept at the bottom if you wish to keep the fish in conditions as close to natural as possible. This substrate, in addition to copying the natural conditions, will develop microbe colonies during decomposition, which are good additional food for the fry. Snags, ceramic pots and plastic tubes of suitable diameter should also be placed at the bottom.

Water parameters: temperature 22-28° C, hardness dH 1-5°, pH 5,0-7,0. Filtration and aeration should be moderate. The aquarium should always be covered and not filled to the brim with water.

Lighting should be low, which should be considered when placing plants in the aquarium and select the species that are able to grow normally in such conditions, such as moss Ancher (Anchor moos, Taxiphyllum sp.).

Betta kratayos feeds on insects and invertebrates in natural conditions. In aquarium conditions, the main food for the fish are a variety of dry food. to improve immunity and enhance colour Betta krataios give frozen and live Daphnii, artemia and bloodworms. The fish are prone to obesity, so be careful not to overfeed them.

Reproduction

For breeding Betta krataios it is advisable to use a separate aquarium, which has a tight fitting lid or covered with a coverslip. This is to ensure that a layer of warm, moist air is formed over the water, which is necessary for normal development of the labyrinthine respiratory organ in fry.

After the male has been courting the female for quite a long time, he swims up to her and wraps his body around her. At this time, the female will hatch a batch of eggs. The male immediately fertilizes the eggs and collects them all into his mouth. The spawning process then continues until the female has fully spawned.

The eggs incubate in the male's mouth for 7-14 days, after which the male releases the fully formed fry. Once this has happened, the producers can be put away, although many accounts suggest that if you leave the parents with their offspring, the fry grow considerably faster.

The fry are fed with micro worms and artemia. Feed the fry should be 2-3 times a day. To improve the overall health of fry need daily replacement of 1/10th of the aquarium water with fresh.

The life expectancy of Betta krataios under aquarium conditions is about 3 years.
