FIX CIN (Clindamycin) is ideal for treating common bacterial fish diseases such as Mycobacterium (Gill Diseases), Aeromonas, and Pseudomonas.  It exerts a bactericidal action on gram positive and some gram negative bacteria.  Keep this medication out of reach of children.  It is intended solely for aquarium use, specifically for ornamental fish and organisms, and not for those designated for human consumption. It should be stored at a controlled room temperature of 59°-86°F (15°-30°C).
