I know this may sound silly but my fire eel is literally my favorite fish I have! I love her so so much and this is why I’m so upset with myself for not looking harder and acting before doing extensive research! So my blood parrot cichlid probably has ICH and my local pet shop gave me this medication and assured me it was good to use with any of the fish I told him I had. He told me remove my carbon filter and add about 20 drops (I have a 75gallon tank) and it says 1 drop for every 2 gallons but start with 20and I should be ok for the first treatment. I thought isolating her would be more efficient but whatever so I added it, it’s blue in color it spread in my tank and within minutes my fire eel went into her boat (only she goes in there) and laid on her side and is breathing heavy. I got so scared so I wanted to see if she would come out and eat. Act normal in any way, and she did! Then went back to her boat lol I pray I am over reacting but I will share the brand and any pictures n videos I can. Thanks in advance
