Cardinal Tetra turned pale after putting in Flourish Tabs
One of my Cardinal Tetras turned completely pale almost see through right after putting 5 tabs in my 20 gallon long tank. As soon as I removed them he turned back to his regular wonderful color. What is all this about? I called Seachem and they asked if I took a picture which I didn't because I wanted to get those tabs out right away! Anyway anyone else have an experience like this? What happened to my fish and any recommendations on future fertilizer?
Thank you in advance
