Table 1: Overview of Fish Diseases
| Disease Type | Symptoms | Common Diseases |
| Bacterial | Ulcers, fin rot | Columnaris, Mycobacteriosis |
| Viral | Lethargy, color changes | Herpesvirus, Iridovirus |
| Fungal | Cotton-like growths | Saprolegniasis, Branchiomycosis |
The Link Between Fish Behavior and Health
Fish behavior is a window into their well-being. Here are some behavioral changes to watch out for:
Appetite Changes
- Decreased interest in food can indicate illness.
Swimming Patterns
- Erratic swimming or floating can be a sign of distress.
Social Interaction
- Changes in how fish interact with tank mates can signal problems.

| Behavior | Possible Indication |
| Reduced Appetite | Illness, stress |
| Erratic Swimming | Water quality issues, disease |
| Altered Social Interaction | Environmental stress, disease |
Diagnosis and Management of Fish Diseases
Diagnosing and managing fish diseases requires a combination of observation and knowledge.
Diagnosis Techniques
- Observation: Regularly check for physical and behavioral changes.
- Water Testing: Ensure optimal water conditions to prevent diseases.
Management Strategies
- Quarantine: Isolate sick fish to prevent the spread of disease.
- Water Quality: Maintain clean and well-filtered water.
