Rid your fish of ich quickly and effectively with API LIQUID SUPER ICK CURE Freshwater and Saltwater Fish Medication. API LIQUID SUPER ICK CURE Freshwater and Saltwater Fish Medication works quickly to heal freshwater fish of icthyophthirius ("Ich") or Cryptocaryon, highly contagious parasitic diseases.

Early symptoms include white spots, darting and scratching against surfaces while more advanced stages can cause labored breathing. This freshwater fish treatment not only helps cure Ich, but it also provides a synthetic slime coat that helps protect against secondary infection, where the natural slime coating of the fish has been disturbed by the parasite. Use at the first sign of "Ich" or white spots. Some scaleless fish are sensitive to this medication, so treat them with 1/2 the normal dose.
