I have a pair of Macmasteri in a 55g planted tank. I noticed yesterday that the female has a noticeably swollen vent, and she's acting somewhat shy. I just did a water change Tuesday, although I haven't been having any issues with water quality. I feed them flake food with weekly treats of frozen bloodworm, and they share the tank with a single Angelfish, some nerite snails, and a bristlenose pleco.
I snapped this pic just before I made this post. She's been mostly hovering in the corner with her mouth slightly open, as you can see here.
