Hello,
I was wondering, are there special conditions, like temperature / light duration, to get the fish into spawning mode ? I am keeping my fish rainbow shiners in my fish room, wich gets no natural light, and while they grow and seem to be happy/gravid, they do not get into a mating mood. (the fish are almost 1.5 years old now)
The temperature is arround 24° (the aquarium is not heated), and the (led) lights are on for 15h /day.
