You better kiss those neons and stipes good bye. The kribs will eat them, even when not spawning. I wouldnt say the female, isnt exactly in the mood for spawning, because her belly isnt deep, so it cant be full of eggs. I have a wonderful 1 and a half inch female who has wonderful colors and hasnt spawned. Bright colors usually mean spawning, but in some cases, it is just that the fish is unusually beautiful and very happy. Kribs need no help spawning, for them it is a sport. Just gove them some good water, balanced diet( might want some frozen bbs), and warm water. What are your water stats? I have known kribs not to spawn with nitrates over 70.
