Did a MASSIVE tank over haul for my mother-in-law on her 15 column tank. Removed about 5lbs of hair algae and scrubbed rocks down with a splash of 3% peroxide-no soaking. Rinsed them off and soaked them in fresh saltwater with pump. While they were soaking I sprayed half the back glass covered in algae with peroxide (15-20ml) and waited 10 minutes scrubbed tank and did a 100% water change. Noticed my 7 year old Maroon clown who survived 2 hurricanes and 3 week long black outs dead 15 minutes ago with swollen gills. No ammonia spike or anything out if the ordinary new saltwater on point and matched temp and running carbon. Moral of the story either remove fish while using larger than normal amounts of peroxide to clean or take it slow...completely my fault lesson learned.

Aaawww . . . rats.
I'm sorry for your loss, Donaldf973. It stinks when we learn things the hard way, especially when it involves loss of life.

It happens part of the learning curve still sucks though. Been reefing 10 years and this is the 2nd death situation to peroxide. First was hurricane Sandy and I went OD on peroxide to keep the oxygen levels up 1/2 cup in a 45 gallon- stupid Petland manager me the desperate idiot. Other clown survived so now its time to pick out something cool for a 15 column that won't pick on the other clown.

Man! That definitely sucks! I'm so sorry.
not tied to peroxide use is my predict. an outlier. No marine fish we keep are sensitive.
stirring up pent up ammonia stores, a hallmark of tank restoration work, is the full suspect based on pics above, the gill observation and the giant sand rinse thread kicked up. not peroxide I bet... it would take a massive overdose, sustained.
the reefcentral peroxide thread has that fish and many more being dosed w much higher levels, for years. sorry to hear about the fish for sure
its fair to review/compare etiologies in loss threads, good to check for trending to be able to make predictions.
we isolate fish when rescuing tanks.
Im sure its insulting for anything (makes my hand tingle sometimes) but it sure is strange to see a hard loss in a light application tank.... good documentation pics.
