In my tank i have a Jardini who basically just hangs out around the middle of the tank. the top of the tank is ussually occupied by my gator gar. THe arowana will NEVER come up to the top for hikari sticks yet my oscar and pacus and everything else does. Is he maybe just scared or just not interested in the pellets? all ive actually seen him eat before were live feeders. i even tried starving him and drenching the sticks in that garlic substance. any ideas?
