Answer

White spots on your fish's fins and body are a classic sign of Ich (Ichthyophthirius multifiliis), a common and highly contagious parasitic disease. If left untreated, it can spread rapidly and be fatal. Immediately quarantine any affected fish if possible. You'll need to treat your entire tank, not just the visible fish. Treatments typically involve increasing the water temperature gradually (if compatible with your fish species), adding aquarium salt, and using over-the-counter Ich medications. Follow product instructions carefully and ensure good water quality. Speak to Dial A Vet via a video consult should you need further guidance from an aquatic vet.
