How can I safely introduce daphnia into my fish tank?

To safely introduce daphnia into your fish tank, first acclimate them to the water temperature by floating their container in the tank for about 15-20 minutes. Then, slowly add small amounts of tank water to their container every 5-10 minutes for about an hour. Finally, gently release the daphnia into the tank, making sure not to disturb your fish. Monitor their behavior and remove any uneaten daphnia to maintain water quality.
