* Plastic bags are not suitable for fish. They lack the proper oxygen and filtration that fish need to survive.
* Fish can quickly suffocate in a plastic bag, especially if it's sealed.
* Fish can become stressed and injured in the cramped and unstable environment of a plastic bag.
Here's what you should do with new goldfish:
1. Acclimate them to their new tank. This means gradually adjusting the water temperature and chemistry of the bag to match the tank.
2. Float the bag in the tank for 15-30 minutes. This allows the water temperatures to equalize.
3. Carefully pour some of the tank water into the bag over the course of 30 minutes to an hour. This gradually introduces the fish to the new water chemistry.
4. Once the water in the bag is similar to the tank water, you can gently release the fish into the tank.
Remember: Acclimation is crucial for the health and survival of your goldfish. Never skip this important step!
