Many fish owners aren’t fully aware of the dangers of parasitic infections in relation to aquarium fish. In reality, parasites pose a very real threat to a fish’s general health, especially if they are not treated properly. There are many different species of parasites that may affect pet fish, each of which may cause a variety of symptoms. Being informed about parasitic infections in aquarium fish is a very important part of overall pet care, since it will allow you to choose the best possible fish care treatment procedure. Here is some of the essential information that you need to know about parasitic infections, and how they can affect your fish’s health.
INTERNAL OR EXTERNAL PARASITES
Because of the plethora of parasite species that can affect aquarium fish, it’s best to first group them into two specific categories: ectoparasites and endoparasites. Endoparasites are organisms that infect a fish by infiltrating their internal organs and tissues. Ectoparasites are parasitic organisms that thrive by dwelling on the outside of a fish, such as on their gills, skin and fins. For the most part, the majority of parasitic organisms that affect fish are ectoparasites, with the occurrence of endoparasites being slightly rare in aquarium fish. In order for a fish to become infected with an endoparasite, it usually requires that they first ingest an organism that is serving as the intermediary host for the parasite, such as an insect or snail. Because of this, it is especially important to watch for parasitic infections when supplementing your fish’s diet with live food ingredients.
DANGERS OF PARASITES
The most commonly cited problem associated with parasitic infections is their incredible reproductive potential. By the time you are able to identify a parasitic infection in one fish, it is possible that the parasites have already reproduced to a point where they are currently in the process of infecting your entire tank. In an aquarium environment, fish are in close contact with all other inhabitants of the tank, causing parasitic infections to spread relatively quickly. Since parasites in aquarium tanks are easily able to transfer from host to host, they have extremely high survival rates in an aquarium environment.
SECONDARY INFECTIONS
In many cases, a parasitic infection in pet fish is also associated with development of some secondary infections. These secondary infections are mostly bacterial, and are usually the end result of feeding activities of parasites on a fish. Since many parasites either infiltrate the exterior portion of a fish’s skin through hooks, teeth or caustic skin-dissolving substances, this often results in open sores developing around the area affected by the parasitic infection. The irritation from these bacterial infections can sometimes cause a fish to produce excess mucus, sometimes resulting in respiratory problems. If a bacterial infection develops in addition to a parasitic infection, it may be necessary to treat with antibiotics. Since treatment for parasitic infections sometimes also uses certain antibiotics, it is very important to consult a veterinarian or fish care specialist about the best combination of medications that will work the best for treating your tank.
