I have a 400 gallon 8x4x20''. Someone in the tank is going on a killing spree. In the last month I have lost both flowerhorns, my royal clown knife and my thin bar datnoid. does anyone know who could be the killer? Water quality is perfect. These fish are just getting beat up over night. My guess is the bass or the ornate. stock is as follows
2 silver arowanas 30"
black arow 26"
marble motoro 18"
