So I've got a 450L tank. I've not changed anything with the tank in months. The things I'm dosing the tank with, the filters, how often I water change, what I put into the tank after I water change, the light period, the food etc... Literally NOTHING has changed.
2 days ago, I turned my room lights off to sleep (my tank lights were already off). The fish went balistic! I turned my room lights back on, and they were fine. I had to get to sleep, and can't sleep with no lights. Turned my lights back off, they were balistic again, then quiet. They're NEVER done this before. Wake up the next morning. 3 of my good bosmani's are dead. Fish I've had for literally years, and just dead. No signs of any disease, anything.
So I did what anyone would do, and did a water change in the case that there was something in the water. A BIG water change (>30%). Turn the lights off that night and the fish went crazy again. It seemed to be just one fish, and old Rainbow I've had for 7 or so years. Next morning, another Bosmani is dead.
I called the local aquarium, and spoke to the expert (the owner), who said it must be the Rainbow that is going crazy (when I called, the Rainbow was running into the glass, other fish, plants, the graven and getting stuck under driftwood. So I did what I had to do, and disposed of the fish (as he would have killed himself sooner or later). I took the day off UNI and watched the fish really carefully. I mean, really carefully. They were all fine, nothing crazy. One thing I did notice, was their on their top lip (if you call it a lip) was white, possibly damanged.
Anyhow, about 5 minutes ago, the lights turned off (I've got it on a timer), then all of a sudden one Bosmani went CRAZY! One that was fine before, just went absolutely mental. Running into everything. He is now swimming at the top of the tank, sometimes swimming upside down.
WHAT DO I DO? I've so far (easily) lost over $200 worth of Bosmani. This is killing me. I've tested the water, and everything is fine. Nothing over the oridinary.
