My AT died 2day. I saw that the night b4 he was all unstable and he wasnt swimming upright as usual. He was slanted when he was swimming. So i was kinda worried but then in the morning he got stable and was better. Then when i went to check on my fish 2day i found him like this
That really sucks. I've had two fatalities so far and both were for unknown reasons. If you have more dats in the tank I would suggest adding medicating with coppersafe just to be on the safe side
