About Fish Diseases and Discoloration
Fish can bring hours of relaxation and are a great hobby. A sickened fish will not show normal behavior in many cases. It is important to observe your fish closely and realize what their normal behaviors are. It is helpful to have a fish guide that can identify specific fish diseases and the proper treatments. Make sure that the treatment will not harm your aquarium's balance. Try to isolate the sick fish elsewhere.
- Invest in a general guide to fish and their diseases. The best ones will have pictures and information listed by categories.
- Be alert for any unusual circumstances with your fish. A sickened fish will show specific signs and behavioral changes.

- Look for any filmy or slimy coverings on the fish surface. Many fish diseases will make the fish look cloudy or dirty.
- Pay attention to any different markings that suddenly show up on the fish. Often these marks and spots will be located on the fins or gills of the fish.
- Investigate any fish that is showing signs of not being able to breathe properly. These sickened fish will often float near the top of the aquarium. Action needs to be taken quickly especially if the fish is gasping or breathing abnormally.
- Assess any fish that are swimming in an unusual manner. Perhaps they are not swimming straight or are slower in their movements. Some fish will stop swimming and stick close by bits of aquarium coral or decorations. They may seem to rub as if they were scratching their scales.
- Check out any fish with rapid color changes. Some species of tropical fish show certain fish diseases by losing their vivid coloration.
