da Seriously fish...
molti altri articoli on-line riportano lo stesso procedimento, e anche un mio amico tedesco, che è stato uno dei primi che ha riprodotto Dario (ma non solo dario dario, ma anche altre specie) mi raccontava di aver fatto le stesse procedure..
io stesso in passato, quando ho riprodotto i Dario ho osservato un procedimento simile..
credo che, se si vogliano ottenere dei risultati, è molto meglio seguire i consigli che indica quest'articolo..

"..Members of this genus form temporary pair bonds and are not usually too difficult to breed provided the tank is arranged correctly. Other species are best omitted if you want to raise good numbers of fry although in a mature, well-furnished community a few may survive to adulthood. Either a single pair or a group of adults can be used but if using multiple males be sure to provide each with space to form a territory; around 12" x 12" per individual should be adequate. In the latter scenario one male will usually become dominant meaning the other males will not be involved in breeding. Set water parameters within the values suggested above, feed the fish with plenty of live and frozen foods and spawning should not present too many problems. Setting the temperature towards the upper end of the suggested range may also help.
As they come into breeding condition males will begin to form territories and display courtship behaviour towards females swimming nearby. During this process they display some intense changes in patterning with the body intensifying in colour. Courtship can go on for days with the female often being chased away then courted again minutes later. The male will make a non-aggressive approach towards the female and appear to 'invite' her into the centre of his territory - if ready to spawn she will follow. The act itself is over in just a few seconds with eggs being scattered in a random fashion on the underside of a solid surface such as a plant leaf.
Post-spawning the female is ejected and the male takes sole responsibility for the territory, defending it against intruders and patrolling tirelessly. If you want to maximise the numbers of fry raised now is the time to remove either the medium (to a container containing water from the spawning tank) or the adult fish as the fry immediately become a food source to any other fish in the tank, including the parents, once hatched. The incubation period is just 2-3 days after which the fry may need up to a week to fully absorb the yolk sac. They are very small indeed and will require an infusoria-type diet until large enough to accept microworm and/or Artemia nauplii. ..."

Fortunatamente ho una coppia che sembra molto affiatata ma ancora non ho visto segni di corteggiamento. Più che altro si limitano a nuotare molto spesso insieme e nient'altro. Fatemi sapere le vostre esperienze! Grazie in anticipo.
