Schistura geisleri is reported as occurring in small groups in nature that search for food in amongst sandy areas, sifting sand as they go. It would appear that this makes them less territory orientated than the very similar S. poculi. It is still wise to provide multiple hiding places for the fish amongst rockwork and pebbles.
