This is the spray that was used. So yesterday and a few days before that my parents bought this spray because they claimed to be “over run” by ants. It was manageable and it’s summer, what do you expect? So they would spray it in random spots in the house where the ants were. Yesterday was different, they decided it was a good idea to remove all furniture and appliances into the hallway and then spray along the baseboards. Here is the problem, my tank is in the kitchen and against a wall with baseboards. They sprayed very close to the tank and the whole house REEKED of this stuff. I tuned my skimmer to accommodate for it the fumes and it didn’t make my skimmer overflow. I had some water mixing in a barrel inside because of the heat over heating my water. I had to resort to bring it inside for that reason. After spraying the whole downstairs I monitored my tank and everything seemed fine but the butterfly was hiding and normally when it’s in the rocks and sees me it come out to beg for food. So this morning I came downstairs and saw him stuck to my ai Nero 5. It was set to 60% maximum for the time being until 930 am as per my schedule. I unplugged the Nero to fish him out and he floated down and twitched a few times, he barely had any boyancy(?) left in him. He wouldn’t make it through the day. I made 25g of water to do a water change today on my 120g. Hopefully this will be enough water. This was literally my first and last copper band, it ate pods, mysis and brine. Super rare and 100% luck. But I was told “it’s just a fish”. If you guys had a copper band and it’s eating frozen and pods you would probably be over the moon.
