I previously had gravel around a year ago when I had my Festae pair in this tank. I am loving the sand though! It is comical to watch the neets use their pectoral and tail fins to dig in it. The only down side is with the previous aquascape my larger Labiatus decided to make big mounds of it at the front of the tank which drove me mad, since the aquascape change so far he is mostly moving it around at the back of the tank which I don’t mind as it’s hidden by the rocks. But at the end of the day cichlids dig and will have it how they want.Really liking your tank. In both our cases it will be play it by ear and adjust as necessary, it will be interesting to see how our tanks mature.
After looking at yours think I am going to swap back to sand.
