het zijn geen levendbarende dus dan zouden er eieren in moeten zitten. Als het al vaker is terug gekomen en verdwenen zouden het inderdaad goed eieren kunnen zijn en inderdaad na een waterwissel leggen ze vaak eieren en word hun kleur feller Dus zou zeer goed kunnen

Reproduction
An excellent choice for those new to breeding fishes in aquaria. Like many small cyprinids it is an egg-scattering spawner that exhibits no parental care.
When the fish are in good condition they should spawn often and in a densely-planted, mature aquarium it is possible that small numbers of fry may start to appear without human intervention, but if you want to increase the yield of fry a slightly more controlled approach is required.
The adult group can still be conditioned together but one or more smaller containers should also be set up and half-filled with water.
These should be very dimly lit and the base covered with some kind of mesh of a large enough grade so that the eggs can fall through it but small enough so that the adults cannot reach them.
The widely available plastic ‘grass’-type matting can also be used and works very well; alternatively filling much of the tank with Java moss or other fine-leaved plant can also yield good results.
The water itself should be of slightly acidic to neutral pH with a temperature towards the upper end of the range suggested above.
A small power filter can be added initially and this should be positioned so that the flow is directed down the full length of the tank.
When the adult fish are well-conditioned and the females appear full of eggs one or two pairs should then be introduced to each container.
Spawning can be initiated by adding small amounts of cool water every few hours in such a way that the tank is gradually topped up and feeding small amounts of live and frozen foods.
The pair should spawn the following morning. The easiest and quickest way to tell is simply to look at the female. If the fish have spawned she will be noticeably slimmer.
The adults will eat any eggs they find and are best removed after a couple of days at which point the power filter should be switched for a mature sponge-type unit in order to avoid fry being sucked into the mechanism.
Incubation is temperature-dependant to an extent but usually takes between 24 and 36 hours with the young free-swimming a few days later.
Initial food should be Paramecium or a proprietary dry food of sufficiently small (5-50 micron diameter) grade, introducing Artemia nauplii, microworm, etc., once the fry are large enough to accept them.
Moest ik nu zeker willen zijn van de eieren best een andere bak opstarten en ze overzetten met veel Java mos dan?
