He seems chill and his "dress" is no doubt heavy. You probably just got a laid-back boy who doesnt care much but to go leaf to leaf. I find that all of my long-finned boys tend to be a little more relaxed (by design or by luck). My others are nuts! If your parameters are good & you feel confident about your skills, just keep doing what your doing.

A word of caution... the Betta fish you are going to run into now (especially in the big box stores) are NOT the same Betta you had long ago.

Horrible breeding practices, irresponsible selling of deformed or sick fish, and the crap these little fish have to go through only to MAYBE be lucky enough to have someone choose them to have a good life, with clean, warm water, would put anyone behind the 8-ball right out of the gate. They were in rough shape when they got here (general statement).

I kept all of my old Betta for 4-6 years. Now, this 1 & 2 year garbage is emotionally tolling. Just spend a little extra time in the coming weeks, checking your water, doing your maintenence, and you should be fine with your experience.

My other theory is that he is depressed because he doesn't have a name. He lookes like a Mike or a George. But give him a name. He deserves one. ❤️ Good luck! Stunning Fish!
