I currently own a 5 gallon tank with 2 goldfish and a pleco. The tank was just treated for high ammonia and the fish were put back in today.
One of my goldfish, a comet, has a cluster of red spots near his tail fin. I did some research but I came up with a lot of possibilities. They were Red Pest, Bloat and Flukes.
All of the fish seem to be acting like nothing is going on, but I still don't want to put it off. My fish mean a lot to me.
The question is... if it is one of the bacterial diseases, should I start treating the infected fish first before treating the others? Or just treat them all at once.
