Well I have had my little pig of a Golden Heart Trigger for about 2 months now. My question is all he does is sit at the top of the tank looking for food. Now I am not a novice, I can tell the difference between a fish stressed and one waiting for his next meal. He will hit the hood with his mouth, bite at the therm, and basically just looks obsessed with food. Is this normal? He never just explores his habitat, he just stares at me while I am on the computer/watching tv like he is just waiting for me to feed him. Is the mentally healthy lol?
