hello everybody,
Hope I am putting this in the right spot, I have a goldfish bought from a bait shop(actually a dzn), they have been in my pond for about 3 weeks now, I have one that has a swollen area,right behind the gill flap, its sluggish(when it doesn't have a net after it). I have put it into a 1 gallon jar with airstone for now. Any ideas on what this could be, I'm thinking somekind of parasitic worm. Have seen similiar spots on bass and bream I have caught, the spot contained a tiny bright red worm. Could this be goldfish problem, ideas to treat pond ? Learning alot by "my trials and many errors" about ponds. ;-)
