Being dwarf mbuna, demasoni will spawn at a smaller size than others... I'm not sure what you're not proud of, though. A pH of 7.8 isn't bad, especially if these fish were tank-raised and acclimated appropriately. If they're spawning, that's generally a size that they're at least comfortable and healthy, if not "happy."
We all miss water changes, sometimes.
Congratulations!
