I currently have a 6" male Green Terror(8" to the tip of the tail) that I have housed in a 30 gal by its self that eats pretty much anything I put in the tank such as Cichlid Staple, Hikari Food Sticks, Spectrum 3mm Cichlasoma Formula and feed frozen bloodworms once a week as a treat. But for the past couple of days, it hasn't been eating anything and is swimming around with its mouth opening and closing. It's still has vibrant colors and still rushes the glass when I put my face in front of it but for some reason won't eat. I've been told that GT's develop bloat at this size due to foods that are high in protein and eventually die. Can you guys help me with this one? I really don't want my GT to die because its one of my favorite fish that I have. So if anybody could help or give an opinion or solution, I'd greatly appreciate it.
