Sorry for replying this thread from last month., but my GT's not afraid of me anymore. Last month I removed all the decorations and hiding places from the tank. The tank was bare except for the substrate No other fishes either. He gradually grew more confident.
Now he comes up when I approach the tank. He used to hide behind the decors earlier. He's not ready to be hand-fed. But i think he's getting there. Maybe i will put the decors back after some more time...
Thnx for all the replies and suggestions
