So sorry for the loss of your first betta fish
I am so glad you found another new friend to take his place. Have you named your new betta fish? How about Prince (aka Prince as in "Purple Rain").
Let us know when he is settled and show us how you've set up his tank along with his other friends. Always keep up with your water testing parameters. We can't stress enough how important this is. I have the API Freshwater Master Kit which you can get at Petsmart or any other store near where you live. Keep swimming as Dory would say.
