did the right thing with kings?

I was happy with the original all in from the fish, and flops don't get much better than this for unimproved kings, so i pushed, the guy to my left wasn't an all out fish, but he wasn't doing anything that made me think he was good.

I'm just checking to see if this was the right move, or whether i should have just raised the pot or something like that. I figure either way all my money would be in centre by the end, so i might as well do it on the flop

I would call knudiebaby's all in but not push all in myself. MAYBE raise it to try to keep Pmass out but not all in. You are only going to be called by somebody with a set or TPTK (MAYBEEEE), which is likely the first person already has, unless you thoughty they were bluffing, so that wouldn't leave many opitions for the second. If Pmass calls the flop all in and you lead out on the turn and he calls then check/folding the river seems like a good idea.
