My fishie has been floating at the top for 3 days now. He's alive and well though... besides his floating on his side at the top. He still responds well to me. And he did eat yesterday and today (he's always eaten a ton of food). He can swim around somewhat normally, but not for long. He can't go down for very long at all before it seems like he's pulled back up. I used to have a filter in the tank, but then thought that this new filter caused this strangeness cuz an old fish died with that filter. Also his one eye is drooping, the side that faces up most of the time..
Does anyone know what the cause of this? And if there's anything else I can do for my fishie? I had figured he would have died by now, but he's a fighter, or it's just not as serious as i think... I do love the little guy and would like to know if I can do anything...
