I'm pretty sure I just got to him too late. I feel terrible, because he was so gorgeous and healthy before I got him. I'm worried maybe I'm the reason he passed >.< I mean, he showed the same kind of symptoms my injured rescue HM did. Still... I suppose maybe its better than the alternatives. At least I gave him and the HM a fighting chance.
I cleaned the two tanks these fish were in as best as I could. Mild soap and rinsed over and over and over again, boiled water, then vinegar and hot water. One of them is now a quarantine for all the live plants that were in either tank. Any ideas how else I can make sure whatever was wrong with the fish isn't stuck to the plants somehow? Will it possibly just die off with no fish in the tank? Or, is not really a big deal?
