Velvet (Oodinium) is generally caused by poor water quality and fish stress. Rapid fluctuation of aquarium temperature, PH, temperature, ammonia, nitrite and nitrate.
Easily prevented by placing fish into a quarantine tank for a week before introducing them into your aquarium.
- Spots that resemble grains of salt or white sand on the skin.
- May be slightly-raised.
- Scratching against objects due to irritated skin
- Clamped fins.
- Gasping at the water’s surface.
- Smaller and more abundant white spots than Ick.
- Remove carbon filters and turn off any UV sterilizers
- Add Ick/Velvet (Oodinium) medication as directed
- Raise temperature to a constant 82° to shorten the Velvet lifespan
- If only a few fish are infected, place the fish in saltwater for 10 minutes, then return them to the aquarium. For Saltwater fish you will give them a freshwater bath instead.
