Hello,
I have about 12 Discus fish who are about 14 months old. They are in a 300l tank and most all of them are about 14 cm or more. Until now I have not observed any pairs forming. Does anybody has experience in triggering the pairing by placing cones? Or is just waiting the best way to go? They are very active and healthy so no problem there. Any suggestions or experiences are much appreciated!
