My clownfish (had for 3 months) has developed white spots on his body, the other clownfish (in dt for 1 month) sometimes lays on the sand. All fish in tank, except the full black clownfish pictured were quarantined (observed) (black hood was first fish). Is this ich or something more insidious? Medications on hand are methylene blue, paraguard, epsom salt, and aquarium salt. What can I use (both with on hand items and in general) to treat this most effectively.
