What’s light during the day but heavy during the night?

My brothers are confident, bossy, robust; While I am uncertain, unsure and unwise. In the end, they will fall as they certainly must: And, in seeking the truth, I shall finally rise.

Arr matey, a wooden home for treasures untold, Stacked high in the hold, like gold they enfold. Ye'll find these in the galley, or on the deck, Hoist them up, and mind yer neck!

I’m an Asian food you see Cheap and in groups I’m found, however I’m not rice.

My first is a food that Dr. Seuss did rhyme, My last means to give someone a hard time. Together, it’s a place to spend a lazy day Relaxing as back and forth you sway.
