Important Aquarium Care Note
Fish illness can be caused by several issues, including poor water quality, stress, parasites, bacterial concerns, fungal concerns, injury, aggression, or unstable aquarium conditions. Medication should be used carefully and only when appropriate for the fish and setup.
PolyGuard does not replace proper water testing, quarantine practices, filtration, maintenance, or accurate diagnosis. If symptoms are severe, spreading, or worsening, a separate hospital tank may be the safest treatment option.
