I went into the garage to check up on my goldfish and one of the larger sarrassa comets is floating on it's side on the surface of the water but is still alive, I examined it's body and I don't see any damage at all on the outside and all my other fish are perfectly normal and I'm really upset because it was such a beautiful fish and I know that there is no fin damage and no scale damage, nothing at all....it just dosent make sense to me....I don't see a reason for quarantine and I don't have a tank for it but I'm just wondering how is it possible that he got like this?, I have other smaller fish who I have had for a shorter time and they are all normal and I'm just really upset about all of this like really really upset.
