I think I'm on the right page now.
Two of the dominant L. hecqui males are finally letting other fish (females??) into their territories. One has a PVC shell it's guarding pretty fiercely, too. Fingers crossed!
Also have some action in my multi tank. Have been siphoning out around 30 fungus-covered eggs a day from tank corners for the last couple days. Shouldn't be long to see some fry in this tank, either.
