$5: 8 Players Left. Too aggressive?

[grayhawk]

Stacks:

Hero: 760
UTG: 1350
UTG+2: 2400

Blinds: 40/80

Preflop: Hero is in BB with K [img]/images/graemlins/diamond.gif[/img], 5 [img]/images/graemlins/heart.gif[/img]
<font color="red">UTG Raises (t160)</font>, 1 fold, UTG+2 calls (t160), 3 folds, Hero calls (t80)

Not the greatest hand in the BB, but I am getting 5.5 to 1 and I am closing the action here, so I call.

Flop: (t520) 6 [img]/images/graemlins/heart.gif[/img], 2 [img]/images/graemlins/heart.gif[/img], 5 [img]/images/graemlins/club.gif[/img] <font color="blue">(3 players)</font>
Hero checks, UTG checks, UTG+2 checks

Nobody likes the flop much, it appears.

Turn: (t520) 7 [img]/images/graemlins/club.gif[/img] <font color="blue">(3 players)</font>
Hero checks, UTG checks, <font color="red">UTG+2 bets (t480), Hero raises All-in for (t680)</font>, UTG folds, UTG+2 calls (t200)

UTG has shriveled up since his preflop min raise. I have him on 2 overcards and finding a reason to get away from this hand cheaply. UTG+2 looks to be making a stab at the pot with an almost pot sized bet with a fairly ragged flop and turn (except for the potential 4 flushes out there.) He does not appear to want action. I think my pair of fives may be the best hand here and decide to make a stand.

How's my line? Was I too aggressive, or did I read the situation correctly and make the right play? Thanks for all comments.
