currently he is in a bowl with about a pint of water. when I started changing water and taking care of water parameters, he got a little better, started swimming a little, so I moved him back to his aquarium (changed water completely, changed gravel, and plants) but there he got worse again.

 

Looks like Dropsy to me, unfortunately... I hope some one will tell me I'm wrong.

 

Am I seeing right... his scales are like sticking out?

yes, they do. I do not know what this is.

 

Sorry, I had scrolled back up to read what you said about appearance and to take another look at the photo... edited my response while you responded.

 

Take some of the water from his container in a cup and mix 1 teaspoon of epsom salt. Stir it until all of the salt has dissolved into the water. Adding a drop of Betta Revive to this mix will help. Add this slowly and gently back into his container.

Stop feeding blood worms for a while. Try pellets soaked in water.

Do 100% water changes everyday with treated aged (set out for a couple days) water. And don't forget the epsom salt mix above.

Do this religiously. Let us know how it goes.
