The main cause of tropical fish diseases in closed aquarium environments is poor water quality.
Healthy water normally means healthy fish, so paying close attention to the conditions in your tank is vital to the well being of it’s inhabitants.
In any enclosed environment, disease becomes a problem if regular maintenance is not adhered to. This is particularly true with tropical fish keeping.
Overcrowding and adding too many fish to the tank is usually the cause of most tropical fish diseases. As a general rule, the smaller the environment, the more likely it is that overcrowding will occur and disease can manifest itself.
Although regular maintenance is required with all closed aquarium environments, the smaller the tank, the more maintenance is required.
The following is a guide to the identification and recommended treatment of some of the more common tropical fish diseases and infections that can affect your freshwater, marine, and brackish water fish.
