Hello,

On Wednesday (today is Friday), I put my 6 year old mail ACF in a nice new 10 gallon aquarium. I also used a new filtration system (an underwater thing called a Stingray?) instead of his old under gravel filter. I noticed he was very agitated (swimming constantly and not eating) so I unplugged the new filter because I was worried about his lateral line. He calmed down, but his water quickly went cloudy and gross. On Thursday I plugged the filter back in all day, but when I got home I noticed he was bobbing his head and kind of twitching. I unplugged the filter again and he seems to have calmed down and the twitching/bobbing has stopped. He has also been singing almost constantly this whole time. He is still not eating.

Do you all think it is the filter and I should switch back or is this something else? I'm worried, I reascued him as a baby from a tiny dried up cup at Wal-Mart and have grown attached to him!
