I hoped you would have respond to my latest post. My blue spotted grouper hasn't ate in a couple of weeks. He use to respond to his food (frozen or live)very well. Now, ever so often he responds to the food but he just hold his mouth wide open over the food, but does not eat it.
He shares a 125gal tank with a 7 to 8 inch puffer, he's about 5 to 6 inches. He's been in the tank for about two months now and the puffer about one.
I've also noticed nickes on the grouper about three weeks ago, so there's maybe a confrentation between the two.
Please help me I'm really in need of help as you can see. I would like you to tell me the next step in resolving this problem.
