Red veins goldfish tail fin and red patches on body
Red veins goldfish tail fin and or veining throughout the body indicate nitrite poisoning. If your tank or pond hasn’t completed the nitrogen cycle your fish may be at risk. Nitrites are the second toxin to form in the cycle with nitrates being the third and final. These two toxins are closely related. Both are produced by living organisms; unlike ammonia, created from waste
Goldfish broken blood vessels
A lot of ‘new goldfish keepers’ and old alike do not understand or know about the nitrogen cycle. In some cases the fish are poisoned again and again; the goldfish keeper unaware. Learn everything you can about the nitrogen cycle. Where you find waste, you find ammonia. When this toxin forms and builds up in quantity good bacteria form to feed on it, converting it into nitrites, and then into nitrates; the end result of the cycle
Goldfish spasms
Other symptoms of nitrite poisoning are spitting food and exhibiting periodical spasms
Goldfish spitting food
Both nitrates and nitrites rob the blood of oxygen. Goldfish kept in healthy water may show fewer symptoms, than fish living in a unhealthy water. In some cases the toxin has already been converted; the symptoms slow to show
Fish that never fully recover from past poisoning may exhibit sudden symptoms long after the fact if oxygen levels drop
