Despite your best efforts, your fish may seem off-colour, lethargic or stressed. Fish are, in fact, susceptible to a range of conditions including white spot, velvet disease and aquarium fungal infection. As a fish owner, it’s important to know how to treat your fish when they are ill, then maintain them in good health. PetMarket has many fish medicine and healthcare products to keep your fish in tip-top shape. This includes snail rid, fish fungus treatment and a broad-spectrum antibiotic for freshwater and saltwater fish. We also stock various quality formulas for fish bacteria treatment, fluke, tapeworm and white spot.
