When it comes to treating fish parasites, there are some medications commercially available that work well. Others can only be prescribed by a veterinarian. Drugs or chemicals placed in the water are commonly referred to as "bath" treatments. Drugs delivered orally are generally mixed in the food, and are meant to deliver systemic effects. Injections may be utilized for cases in which small numbers of fish are involved. Bath treatments are the most variable, in that a specific concentration of the chemical is placed in the water for a specific length of time. As a rule, lower concentrations are used for longer periods of time and vice versa.

Just like any other creature, your fish can suffer from disease and parasites. When fish have parasites they are very contagious. If a fish actually has parasites, it's highly recommended to separate the fish in question from all the other aquatic life in your fish tank. Taking the fish out of the aquarium into a portable container is probably the best way to do so. Otherwise the parasites will most likely spread through the whole fish tank until all fish are infected. Below is a list of seven parasites that are common among tropical fish: Anchor worms – these parasites are females and have an anchor shaped head, which they use to burrow its way into the flesh of its prey. Once they bury themselves into the fish there may be a little bit of bleeding on the fish where the head has attached itself. You may also be able to see a little worm or tentacle that is white protruding out from the spot where the parasite is attached. Because this parasite’s head is anchor shaped it is difficult to remove, and if pulled out by force may cause the fish to suffer a bleeding wound.
