I recommend the book "What a Fish Knows": https://www.amazon.com/What-Fish-Knows-Underwater-Cousins/dp/0374537097

I’m midway through the book “What a Fish Knows,” which pulls together much of what is currently known about some of your questions. You might enjoy it: https://www.amazon.com/What-Fish-Knows-Underwater-Cousins/dp/0374537097/ref=nodl_

Sounds like a good start, lol. r/bettafish has lots of good info in their sidebar - just cycle the aquarium first - which the sidebar here has the info. 5.5gallon sounds great. Only exception being the petco "king" bettas which I'd suggest 10g or larger. Get a good pellet (omega one or new life spectrum) add once a week frozen daphnia (prevents bloating and is yummy).

Also, if you want to put yourself through another emotional wringer with fish read What a fish Knows by Jonathan Balcombe.

I read this book a little while ago and was pretty surprised by it. You might find it worth considering.

PETA has long had a campaign against fishing.

["What a Fish Knows"] (https://www.amazon.com/What-Fish-Knows-Underwater-Cousins/dp/0374537097/) is a really great book about how fish should get greater consideration. I highly recommend adding it to your summer reading list.

Check out "What a Fish Knows" by Jonathan Balcombe (https://www.amazon.com/What-Fish-Knows-Underwater-Cousins/dp/0374537097). I just started reading it, but so far it's been a fun look at fish intelligence.
