I would try what I found to help with getting spawns. I would fast the fish for a couple days, and continue (or possibly increase) your waterchanges. Some fish will get too preoccupied with the continuous feeding to not focus on spawning. The fasting for a couple days may bring them into spawning mode.danhoy said:I do water changes 2 times weekly and all parameters are near perfect. I feed 2 times daily using 1mm NLS. I feed slightly heavier then probably should, but figure I'm ok since I do bi weekly 25 % water changes.
