Hand from a live game. Please advise.

[purnell]

The game is loose and very aggressive (I'm having fun not winning).

Purnell is bb with A5 hearts.

UTG (Maniac) raises, Weak-tight folds, Fishie calls, Tough LAG calls, Tricky calls, 2 TAGs fold, I call. The pot is now 5 BB.

Flop is 864 rainbow with a heart, giving me the bottom end of a gutshot, a backdoor nut flush draw, and a weak overcard.

I check, Maniac bets, Fishie calls, Tough LAG calls, Tricky raises, I fold. (Pot is 7.5 BB minus the rake)

Standard?
