I transferred over quite a bit. Unfortunately, I did the transfer right after posting again (too anxious to wait any longer) I did dig a little deep while transferring my gravel over, so her water got a little cloudy. We got the filter going, and now the water is nearly clear.
Lucky for me, my sister was able to grasp the waiting before getting fish thing. I pulled out the book that helped me get my aquarium started and showed her how to set up an aquarium, and how you have to do it slowly, and she didn’t get upset. Her beta will go in as soon as the water is livable, then we will get her some tetras after that.
When I told her that other fish could live with betas she didn’t believe me. But now she’s very excited that her beta can have tank mates. We flipped through the book and when ever she saw a fish she liked she asked if she could have one. I told her which fish she could and couldn’t have, and she’s pretty happy with the possibilities.
