Nighty Night – Fish Sedative for Koi and Ornamental Fish
Nighty Night is a professional-grade liquid sedative formulated to safely calm koi and ornamental fish during handling, inspection, transport, or minor procedures. It reduces stress, limits struggling, and allows fish to be examined or treated with minimal risk to the fish or handler.
Nighty Night is not a medication and does not treat disease. It is a handling aid designed to make necessary fish care safer and more controlled.

Calm koi and ornamental fish for physical examination
