It all began in 1985, when Mr. Hector Luzardo received matched pair Rocio young (then cichlasoma ) octofasciatum as a gift from a friend ...
This pair is already reproducing in the aquarium general, in which they are posted, but the eggs disappeared always within a few hours due to other inhabitants of the tank. soon were moved to their own home, making spawning were entrancing amount of eggs - about 2000 seeds, and fry just after hatching, was caught in another aquarium. When small fish were about 20 days, Mr. Luzardo fished a few dead animals, which drifted on the water surface, and their fins were torn and chewed.
Their color, however, seemed a bit paler than usual, but the owner concluded that reason must be the missing scales. next day, another four fish were in a similar condition, and a few days later. It soon became clear that there is more than just a stronger attack on the weaker sibling of art. Several fish in the tank clearly looked and behaved differently than the rest.
After detailed observations, it appeared that about 1 / 4 grupowała fry in one of the corners of the aquarium, looking at this for a bit smaller and more slender than the rest of the siblings. Fish were once overfished to a separate tank. After several weeks, the color of young fish slowly turned into a bright turquoise and it became clear that grow into something quite unlike their parents.
But color is just one of the differences. It turns out that the variety "Blue Dempsey", which first saw light of day then, it has usually more elongated body has a more diverse range of possible designs on the scales and the absence in her large dark spots on the sides. Their appetite is not as indomitable, as is the case with standard specimens, grow too slowly, but eventually reach similar proportions. They are also more leniently disposed. Despite such marked differences compared with the rest of the siblings, parents will recognize without problems in a turquoise blue fry their offspring and do not treat him differently.
As for the mystery their origin and why no one else was able to reproduce these fish is that pair of two "blue varieties" pielęgnicy niebieskołuskiej never effectively do not abound, and even if their offspring will be weak and die after a few days. So in order to succeed, you must choose one "blue" cichlid, and one simple, but one that carries a "blue" gene In this way, about 50 percent of the offspring will be "blue". Draw the fish should be carried out very carefully, however, since "blue" variety often leads battered by the stronger and more aggressive standard form .
Ot, and the whole mystery:)
