Thanks, yes, beautiful species. This group is in ~25L of water in a half-filled 40L (10 US gal) aquarium. There is plenty of space and caves of leaves for them to hide and have small territories, yet they know where the food will be at feeding time and they all come out to that area to feed. I observe all 7 of them feeding, so there is no lack of getting food due to a larger area.
