We have "Nelson" for over two years. He was my daughters fish. I have had tropical fish most of my life but never a beta. Nelson went to college and has now been back home since January. About a month he started missing the chomps on his food. He sees food a few inches away but can't chomp it when he gets close. He swims, he goes to his feeding spot, he reacts positively when I aproach his tank and he goes all happy when my wife talks to him. He just can't eat. I tried FD blood worms and he chases them around but can't get them in his mouth. This is now day 8 without eating food except for one pellet my wife got him to eat after 20 minutes of attention. Are there any tricks that I can try to get food into Nelson?
