Scientific Name: Brooklynella hostilis
Identification: As the parasite causes respiratory difficulties, the infected fish show rapid or labored breathing and may swim close to the water surface in an attempt to get sufficient oxygen. The gills may hemorrhage and small red spots or skin lesions may be present.
Treatment: Formalin baths for 30 to 60 minutes, or as long as the fish can take it, will work to kill the parasite
Prevention: Quarantining a fish for a number of weeks before it is moved to a display tank will allow you to watch it for signs of parasitic infection.
