Angelfish Disease
The following are the diseases that most commonly infect angelfish.
Angelfish Virus
A Potentially deadly disease. It is highly infectious. All exposed angelfish that are not immune will come down with symptoms within 2-3 days of exposure, usually quicker. If you suspect that a quarantined fish has this, you should destroy the fish. The risk is too great to keep such a fish around. There is no medication for this virus. The fish's immune system must be relied upon for the cure. Symptoms: Clamped fins, excess slime, listless with nose pointed up slightly, usually towards the back of the aquarium. It has an approximately 3 week infectious period. This disease is so undesirable, because if an angelfish survives the virus, it will likely become a carrier for up to six months. This can put an angelfish breeding operation out of business very quickly. These symptoms can also be caused by other infectious diseases which may be secondary or tertiary infections, that are unrelated to the virus. The object is to keep the angelfish comfortable while giving the immune system time to kick in. Remove any bright lights from the aquarium and treat with an antibiotic to prevent secondary infections.
