velvet-oodinium

The Cause:
Velvet (Oodinium) is generally caused by poor water quality and fish stress. Rapid fluctuation of aquarium temperature, PH, temperature, ammonia, nitrite and nitrate.

Prevention:
Easily prevented by placing fish into a quarantine tank for a week before introducing them into your aquarium.

Symptoms:

  • 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.

Treatment:

  • Remove carbon filters and turn off any UV sterilizers
  • Add Ick/Velvet (Oodinium) medication as directed

Additional Treatment:

  • 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.
