Leopaldi and Manacapuru

All I have a bout six of each of the above and am struggling to get them to be remotely interested in spawning. Water is okay as I breed Discus on the same system, but am really struggling to get them switched on any hints or tips ??

Plenty of live food (white worm and chopped up earth worms are good), daily partial water changes & when they loog good and fat a water change with nice cool water at the same time as a storm is coming as the change in air pressure seems to trigger alot of spawning.
Also make sure they feel happy and secure in their tanks and some Almond leaves don't do any harm
Fingers crossed for you , Lisa
