Pepper was just adjusting and now sounds like one happy little boy. See you worried for nothing. He sounds like he is doing fine and loves his new digs. Congratulations.
I know there are several who do not care for the 5 gallon hex tanks but the first 2 years I had bettas that is what they all lived in except for a brief period of time when I had a large vase with a heater and filter and a 3 gallon Eclipse tank. They did fine and in some ways acted happier than they do sometimes in their 12 gallon Eclipse tanks. So I see nothing really wrong with them and they far surpass the small cups they are in at the store so do not let anyone tell you that you have done anything wrong.
And besides, Pepper seems to like where he is at now...witness the bubblenest. And after all is not that the thing that really matters? Congratulations to you and to Pepper. You both sound smashing!
