Add your betta
First, slowly and carefully add some of your tank water to the container in which you received your betta. Allowing the new water and old water to mix will make the water easier for your fish to adjust to––if the habitat water is much colder or warmer than the previous water, mixing waters will help allay any shock for the fish. Next, tip the cup into your new aquarium, but try to add as little water as possible from the container to the new home, since sometimes water from the pet store can carry diseases and other things that you don’t want in your new tank. Be gentle as you tip in the betta.
- Avoid netting a betta if possible, as this can damage the delicate fins. If you need to pick up a betta, try to use a small cup to scoop him/her up with care.
