New Life Spectrum® is pleased to provide this resource to assist aquarium keepers. It covers a few of the more common illnesses found in tropical aquarium fish, but isn’t a complete listing of fish diseases or disorders. Any issue included, or excluded, from this listing of articles shouldn’t be taken as a statement of any disorder’s importance, priority or lack thereof.
Read MoreWhile it shares a name with the freshwater variety, Marine Ich is a distinct parasite. It’s one of the most common diseases that afflict marine fish in aquariums. An early sign of infection is that fish may exhibit behaviors in which they attempt to ‘scrape’ themselves on rocks and other surfaces. In fact, observing your aquarium for these behaviors may allow you to catch infection before the outward symptoms are visible.
Read MoreWhile it shares a name with the marine variety, Freshwater Ich is a distinct parasite. It’s one of the most common diseases that afflict freshwater fish in aquariums — and it’s the name of this parasite that lends both it and the marine version of the disease it’s common name.
Read MoreThe term “Hexamitasis” covers disorders caused by a range of flaggellate protozoan parasites in both marine and freshwater environments. Because it can cause lesions on the head, it is sometimes referred to as ‘hole in the head’ — but is distinct from the nutritional disorder that can often share this descriptive.
Read MoreEvidence suggests that a leading factor in development of this disorder is vitamin or mineral deficiency (and/or ongoing stress to the fish).
Read MoreThis disease, like many aquarium disorders, has a freshwater and marine variant that share names but are caused by different specific organisms. The marine variation is caused by the dinoflagellate parasite Oodinium ocellatum (also known as Amyloodinium ocellatum).
Read MoreThis disease, like many aquarium disorders, has a freshwater and marine variant that share names but are caused by different specific organisms. The freshwater variation is caused by the dinoflagellate parasite Oodinium pillularis.
Read MoreWhile different diseases, both Brooklynellosis and Uronemosis are caused by cilliated protozoan parasites. Brooklynosis is often also referred to as Clownfish Disease due to it being somewhat more common in these fish — although by no means is it restricted to Clownfish.
Read MoreFin rot is a clinical-sign rather than a disease caused by a single specific organism, and the term covers disorders caused by a grouping of possible bacteria in freshwater fish.
Read MoreVarious forms of the Aeromonis bacteria are responsible for a variety of illnesses in fish. The Aeromonis hydrophila bacteria, for example, is one of the possible culprits in fin rot.
Read MoreThe term ‘dropsy’ when referring to issues with goldfish and koi (salmonid fish — of which carp related fish are a part) can be frustrating. This is because ‘dropsy’ is a clinical-sign rather than a disease caused by a single agent or organism.
Read MoreA variety of parasites are possible to infect aquarium fish that are outside the realm of dinoflagellates, protozoans, bacteria and other micro parasites. This article isn’t meant to cover them all nor be a complete reference. However, it is worth briefly surveying a few of the more common offenders.
