Unfortunately, aquarium fish and organisms can get sick or injured too. Aquarium medications help you nurse your them back to health. We carry the most reliable aquarium medicines for bacterial, fungal, and parasitic infections, as well as topical treatments for wounds. Aquarium stress (from overcrowding or improper water conditions) weakens fish immunity, slows healing, and is a main cause of illness, so make sure you are also managing stress in your aquarium.
We strongly recommend medicating sick fish in a quarantine tank, while performing water changes and thorough cleaning of your main tank. If you have to treat your main tank, stop carbon filtration first, then resume afterwards to remove the medicines from your water.
