I have not been doing this long, but in the last 3 days i've had 2 fish with white spot, 1 which has died. I now have 1 that may have Dropsy...One pet said it was and the other thinks it is constipation. So we will try the 2 drops of epsom salt and see if that works and it is constipation. Symptoms protrusion of eyes and pinecone abdomen
