Aquarium fishing is an important sector in aquaculture, which is carried out for economic and hobby purposes. Diseases are one of the most important economic losses in this sector. Parasitic infestations have an important place in aquarium fish. Planarians are flatworms that can live in both freshwater and marine waters, appearing in many shapes and forms.

In this study, fish mortality and treatment due to planaria infestation in Electric blue Jack Dempsey (Rocio octofasciatum) and parrot cichlid aquariums were investigated. In a freshwater aquarium with a 400 liter capacity, consisting of 13 fish with an average length of 12 cm and a weight of 50 g, the infestation of planaria was formed as a result of overfeeding and equipment contamination, with a mortality rate of 60%. For the treatment of morphologically identified planaria species, it was observed that the virulence was reduced and the development of the parasite stopped with the use of 3ml/100L FMC (Formalin-Methylene-Malachite) suspension.

As a result of the study, it was seen that the water temperature was increased to 31 oC after removing the infested fish from the aquarium in planaria infestation and disinfection of contaminated tools and equipment after FMC application could get rid of the infestation.
