I came home from work today only to realize one of my young Honey Sunset Gouramis was dead. There are 11 other fish, one other gourami, in the tank. This fish was fine, my tank is fine, I have checked everything out. I am not sure what has caused this to happen. The fish was only about half grown. All the other fish seem to be acting normal, I am going to be on the look out. Was wondering if there is anything special I should do.
