Super Ick Cure is a medication for the treatment of freshwater ich (Ichthyophthirius) and other external parasites including Trichodina, Chilodonella, and Oodinium (velvet). Clinical symptoms for ich include visible white spots on fins, body, and eyes, scratching against objects in the aquarium and flashing or rubbing on the aquarium gravel. Velvet appears as a fine yellow dust on the fish. Most external parasites are too small to be seen without a microscope. With the exception of ich and velvet, often the only symptoms are labored breathing and lethargy. Positive identification can only be made after a detailed microscopic examination of the fish's gills, skin, and fins. These symptoms can be caused by a variety of factors including poor water quality, fighting, rough handling and over-crowding in addition to actual disease pathogens. Be sure to maintain proper water quality and a suitable aquatic environment for your fish.
