Question for you guys, I've been trying to break my gatf off live for over two weeks. He's sure stubborn as hell. Has not had a single bite of every offering I've tried. My rays and other fish gobble up loaches and market prawn. How long do you think an 19" gatf go for without anything to eat. I find him just coasting infront of the wave makers and on edge whenever I approach the tank. I am sure he's very hungry but just too used to live feeders.
