Fish Medicine & Healthcare

Your aquarium is a tranquil and beautiful part of your home's décor. But at one point or another, you may have to deal with some things that aren't so pleasant, like fish diseases in your aquarium. There are a few factors that can cause fish fungus and bacteria to form in your fish aquarium, including poor water quality, a large amount of decomposing matter, or fish with preexisting infection or injury. No matter how it got to this point, treating what ails your fish needs to be addressed quickly with a quality fish fungus treatment. Tetra Lifeguard All-in-One Bacterial and Fungus Treatment can be used to treat and prevent many of the diseases that can afflict fish including ick, mouth and fin rot, flukes and ulcers. It contains the powerful oxidizing action of HaloShield, which destroys microorganisms and can also be used as a preventative when adding new fish. Use API Bettafix Natural Healing for Betta Fish if your Betta fish are suffering from fish diseases such as ulcers, mouth fungus, or fin and tail rot, or if you see red ulcers, slimy patches or cottony growths. It's a natural antibacterial remedy made with healing Melaleuca (a variety of Tea Tree) to help heal wounds and repair tissue damage. It's important to remember that tanks with fish that have reoccurring fish diseases the require fish parasite treatment so you need to be examined for tank hygiene, filtration and water quality. A healthy tank will rarely have fish fungus issues and you won't have to use a fish fungus treatment. To take tank cleaning a step further look into purchasing some fish water care treatments and be sure to have the right fish tank filters in your aquarium. Keeping your fish's water clean is the first step to providing them with a great new home. Whether you need some new fish food, fish tank accessories or any other fish supplies Chewy's online pet store is where you can go for great deals today!

The medication you choose should have detailed instructions, but you may want to contact an experienced aquarist or aquatic veterinarian for expert guidance.

Do fish need antibiotics?

Fish do sometimes need antibiotics, particularly when they are suffering from common bacterial infections like Aeromonas or Pseudomonas. Talk to your vet about appropriate treatments whenever you suspect your fish are ill.
