Parasitic disease
- Unbuffered MS-222 should never be used; it is very acidic which can not only damage fish epithelium but can also cause some parasites to detach from the fish.
- Tissue should be examined for morphology and for the presence of parasites, bacteria, or fungal elements.
- Wet-mount examination of fish tissues is crucial for diagnosis of most parasites.
