One of my two Koi Angelfish that I got 18 months ago has been in perfect health for all of his (or her, not sure) life but last night and all day today has been sick. I noticed a big difference tonight since when I usually come up to the glass, both of my angels will approach but tonight only one did. I noticed the other one staring at the back wall being unresponsive to me. I knew this was not normal so went to get a closer look and noticed that both of his eyes were hazy and foggy. When I fed the fish he ate nothing at all and then started swimming on his side. Then, my Sailfin Mollies proceeded to attack and bite him (which they have done in the past but he normally fights back) and he did nothing about it. I am very worried he may be dead by morning if nothing large happens to help him. He is currently in a 10 in wide net submerged in the top of the tank and is upright but appears to be in affect blind, or at least with VERY more vision. I put in some Stress Coat into the net to see if that helps but if anybody out there knows what to do please respond ASAP. I would hate to lose my favorite fish which may ultimately be what happens. I will stay up later tonight to keep an eye out for any responses so please post no matter what time it may be. If anything else happens I will update this.
