How Can You Get Rid of Parasites in Fish?

Parasites are organisms that establish an unwanted symbiotic relationship with host species. To a certain extent, parasites are passive predators that don’t kill their prey because doing so will result in the loss of the host. In many cases, parasites cause harm or disease. However, a few parasitic relationships are actually beneficial to both host and parasite. Biologists who research parasitology will tell you that virtually any ecosystem or creature can serve as a habitat for parasites, even you and me. These organisms have a potential to thrive as long as they can find hosts, which means they could find a way into your aquarium or pond.

How Parasites Enter Aquariums and Garden Ponds

Transportation is the most common method of introducing parasites in ornamental aquatic habitats. Fish and invertebrates are the most common vectors. In reef tanks, introducing “live rock” such as coral pieces can also result in parasitism. Some of these organisms are mostly pesky. However, there are various parasites that can threaten the health of fish, thus causing an unhealthy imbalance in the ecosystem. Garden ponds that attract frogs, insects, and birds are also at risk of developing a parasite infestation.

Aquarium Parasite Prevention

Always get your fish, plants, and invertebrates from a trustworthy aquarium supplier, such as Aquatic Warehouse. Ask how long the fish have been in the shop’s tanks, and try to steer away from brand new arrivals since they may not yet show symptoms of hosting parasites. Dosing the aquarium with supplements and frequent water changes and using UV sterilizers (https://www.aquaticwarehouse.com/ultraviolet-sterilizers) can also prevent the spread of parasites.

Types of Fish Parasites

Ichthyopthirius multifiliis is a parasite species all fish keepers should be mindful of. The disease caused by this parasite is known as ich, and it can be recognized by white spots that develop on the fins and scales of aquarium fish. Moreover, the hosts develop symptoms of desperation as they try to dislodge the parasites by rubbing themselves against rocks and gravel. Sweet water polyps, also known as hydra, attach to algae and wait for shrimp and smaller fish to come near their tentacles. Anchor worms are larger parasites that can be problematic in koi ponds. Another organism to watch out for in garden ponds is the fish louse, which causes inflammation in addition to bleeding and secondary infections.

Treating Tanks and Ponds for Parasites

There are three methods for killing parasites in aquariums: medication, temperature control, and manual removal. Dosing the tank with appropriate medication and increasing the frequency of water changes will often take care of the problem. A good practice for ensuring you get the right medication is to take photographs of the parasites or the affected areas. The staff at the aquarium shop should be able to identify the issue so the right medication is used. Increasing water temperature to about 82 degrees for a couple of weeks will speed up the life cycle so the medication can eradicate the eggs and parents of the parasites, but you’ll have to ensure all species in the tank will be able to handle it. With regard to garden ponds, it’s easier to add the right chemicals than to adjust the temperature.
