Common Tropical Fish Diseases
There are a number of common tropical fish diseases, some of which may occur in spite of careful husbandry. Among them are:
• Dropsy; this abdominal swelling is among the most common tropical fish diseases currently observed in residential fish tanks. The fish appears listless, it is bloated, and it ceases a majority of movement. Bacteria are to blame for this condition and while it is not always fatal, the outlook for fish suffering from dropsy is not good. Specially formulated anti bacterial water additives may be used in the early stages of the disease to reverse the effects.
