Check this out. I have raised three gars since fingerlings. Two alligator gars and a florida spotted gar. Well, I sold one of my alligator gar and moved my other alligator gar into another tank. Since then my spotted gar has not eaten for over 3 weeks and he was a real pig before. He also just mopes on the bottom of the tank. None of the other fish bother him or anything and all other fish in the tank with him eat like mad. Well tonight I decided to move him over in the tank with the alligator gar. Immediately he began swimming with his long lost friend and began eating. Do you think fish miss other fish? I have never experienced this. Anyone else?
