I'm not one to go dumping chemicals into the tank, moreso because I don't trust myself to diagnose ailments correctly. I've begun 5g water changes twice a day now before and after work and will try to wait it out. His condition is getting worse in the sense that when I feed them, he makes the effort to get up to the surface, but then makes no effort to eat. The other angel chases the flakes where ever the current takes them. I know it's not a matter of him not liking the food because he's been eating like a pig up to this point.
Since he's been quite inactive I've had plenty of time to examine his body and I see no signs of infection anywhere. They both have red coloring around the gill, but I think this is more common to the koi coloring than a sign of disease. I'm so upset. I thought for sure I could provide them a great home. In the two years the tank has been up, Ive never had an outbreak of disease, not even ich so I wonder if he brought something with him from the LFS. The Danios and Barbs are still doing fine, but they are pretty hardy so maybe there was something in the tank and they just battle through it. In the interim, would you recommend maybe a slight addition of aquarium salt and a slight temperature increase? Thanks for the help!
