Hey guys. I just wanted to share my mistake I made today (and utterly shame myself for my stupidity). I had a yellow Tang in my 66g DT (total water volume 75 gallons with sump). It's been living happily for the past 2 months and was active this morning. My chaeto originally exploded in growth but was recently melting away. I went through many posts that recommend dosing iron to bring the chaeto back to life. So I grabbed the seachem flourish iron that I've used for my freshwater planted tanks and dosed enough for only 50 gallons, so roughly 2/3 of the recommended dose on the bottle. I should realized that this was too much as I shouldn't be dosing based on the entire tank volume because it's not like my chaeto grows out of control in my DT. 3 hours later, I see my favorite fish, my yellow Tang, dead on the sand. My clowns, wrasse, and watchman goby are fine. There was no sign of any other diseases on it and my last new fish I introduced was months ago and they all go through copper quarantine. I made a quick Google search and apparently this has happened to other people as well. I'm angry at myself for letting this happen and not doing a thorough investigation prior to dosing. I just wanted to share this experience to others who may not know about this possible sensitivity for tangs.
