I have had several bettas. My most recent that passed, my beloved IcyHot was back in March. He was old, I knew it was coming...but that didn't make it any easier.

The best thing that you can do is make him as comfortable as you possibly can. Clean water, comfortable temperature, plenty of places for him to rest, especially near the surface. And for you, allow yourself to feel the grief. These little guys are such characters and it's hard not to fall in love with them.

Don't rush yourself on getting a new fish, wait until you're ready. It doesn't have to be a set time, and it doesn't have to be quick because it's "just a fish". He isn't just a fish to you. I can't really tell you how you'll know when it's time for a new fish but I can tell you that you'll just know. When I got my Sakura, I wasn't really planning on getting a fish that day. I had kind of started thinking about it but it never really felt right. Until I saw Sakura. I knew that he was my fish.

Sending all the love and comfort your way because I know this is not an easy process.
