White Spot - Ichthyophthirius (Ich) Ich attacks the skin and gills of the infected fish. Ich is a parasitic infestation that is a very common pest among hobby aquarists. It can be introduced by rapid changes in water chemistry such as temperature or ph (these weaken the fishes immune system leaving them susceptible to disease), poor water quality, or bullied fish. Ich is easily treated if caught in time. Once symptoms are observed, treatment must be swift. The life cycle of ich is about 4 days, if treated, it will have to be a minimum of 4 days. While the ich is in cyst form, it cant be killed by medication so you have to treat long enough for the cysts to hatch into its free swimming form.
Symptoms: Fish will flash or scrape its self against aquarium décor, appearance of small white cysts or "sprinkles of salt" on the body or fins, loss of appetite, rapid gill fluctuation (breathing heavily), exhaustion, isolation, fish may hang out near the surface or water return.
Treatment: There are many different treatments available for ich, just goto any fish/pet store. Many people believe that the addition of aquarium salt at the ratio of 1 tablespoon per 5 gallons of water, to be very effective along with the commercial treatment, and upping the temperature to 82F.
