I'm kinda concerned about one of my guys. My wife noticed a couple of weeks ago that he was keeping is tail curled and only using one of his fins and floating on the bottom. He was fine when i got home. I saw him do it again two days ago right before i feed them as soon as food hit the water he was up an swimming like normal. Today he was doing it again so i put some food in and he's back to normal. I checked the water no amonia, no nitrites and no nitrates. I was feeding them twice a day and cut it down to once a day. Some one tell me you've seen this or you know what the heck he's up to.
