They need driftwood to eat on to stay healthy. Also, veggies on occasion, shrimp pellets, algae wafers. Use these items as occasional treats, driftwood is actually the main diet. Cute little fish but can be territorial inside their own species in smaller tanks. It's usually limited to some pushing and shoving, no damage normally. They get along well with other peacefull bottom dwellers. Mostly noctournal, when you see them it's always a treat.
