I've tried to cross zebrafish but without any success. My founders 
are 16 months old ( I also tried to cross young adults that are just 
4 months with the same results). Fish are kept in a 14 h light/10 h 
dark, and are fed twice a day with frozen brine shrimp. I don't 
believe they are overfed. I set up the crosses in the late afternoon 
using breeding trap (white mouse cage with the steel mesh into a 
clear one) fill with fish water + fragment of plastic greenery. The 
whole trap being placed on a black surface. I'm very carefull when 
netting the fish to avoid any stress. The next morning I wait until 
1h30 after the lights on to check for the breeding. What am I doing 
wrong? Does anybody has suggestions for efficient breeding
