Flopping quads at NL

[Scott_Baio]

playing 9 handed nl, on the button with [5,5] we all have each other just about covered. 2 limpers to me, I limp, sb completes and bb checks

Flop comes [5, 5, 10] with 2 hearts

checked to me, what do you do? I check.

turn is 6 not heart [5, 5, 10, (6)]

Checked to me, what do you do? I bet min. 1 caller

river is 8 of hearts, flush got there [5, 5, 10, 6, (8)]

Checked to me. I bet min again, hoping to get raised, caller just calls down.

I don't think I maximized vaule there, would anyone play anything differently? Would you bet a lot, and hope someone else picked up a hand?
