Blood worms along with the pellet stuffed earth worms ,your doing better than most .you got them eating pellets. You can add shrimp , fish,insects and other foods along the way.
I don't think we all feed are bass one or 2 foods only and we all will never agree on water changes or temp or size of tanks. All we can do is do the best we can.
Bass like fishes of any kind takes some research, time ,space and some cash to keep heathy happy and very cool looking.
Just my 2 cents worth. Space, water, food and time
