Fish Crazy
I noticed my Kuhli Loach floating at the top, and it was heart-breaking to see that he was up there. But when I went to scoop him out, he went crazy and shot down to the bottom of the tank. He did it again later, and I am now confused. Is this normal behavior? Or is it caused by not enough oxygen, new fish around, or a medicine I am using currently?
