Did a 100% water change today, and I used a different water conditioner than before. Jalen seemed fine for a while, but then he started acting weird. He hung out in the top corner of his tank, head floating, fins hanging. When I went over to get a look, he started darting around his tank like crazy for almost a full minute before sinking down and standing straight up on his tail.
He's acted like this once before, when perfume got into his tank. I knew that new conditioner could be shocking, so I had been slowly adding it to his tank with every water change. He's now in a little tubaware with his old conditioner and some methylene (sp?) blue. He will still drop onto his tail every once in a while, but he's wiggling his pectorals and coming up for air, and when I tempted him with a pellet, he gobbled it up.
I'm going to do a 60% water change, and dose the new water with the old conditioner. Why is my fishie freaking out?
