Breed­ing of P. quin­decim was cre­ated by Peter Finke
Some days ago I received four pairs of P. quin­decim from Bern­hard Lukiewski (Berlin), who is our best spe­cial­ist for that species. He breeds this species since long, at least since seven or eight years. Two of the pairs will go on to Helene in some weeks time when I shall visit her. Now, the four pairs inhabit four small tanks for their own (12 liters) with­out any tech­nique besides light­ing.
Two things are remark­able:
(1) Two of the four pairs have spawned already. That is not very spe­cial, for we know that Paros are often insti­gated to spawn by water change or change of tank. So this indi­cates nor­mal­ity. But together with the sec­ond point it is remark­able, nev­er­the­less:
(2) All quin­decim we have in Europe stem from the same group of fish that was imported by Glaser (Rodgau/​Germany) about ten years ago under the name of “spec. Man­is­mata”. The species was not sci­en­tif­i­cally described at that time; this hap­pened only in 2005. We had often prob­lems of fer­til­ity and health with Paros from the third or fourth gen­er­a­tion onwards, but noth­ing of this is to be noted with quin­decim. Some­times we had fish not equally colour­ful than in the early gen­er­a­tions, but even this changed again in the next gen­er­a­tion when given good nutri­tious food and water with a low germ den­sity.
These fish are at least the tenth or twelfth gen­er­a­tion, and they are fully healthy and colour­ful. This is remark­able: the colour­ful nor­mal­ity of healthy quin­decim in such a high gen­er­a­tion that was never freshed up with new blood from a sec­ond import.
