Large Vintage Murano Glass Fish?

This is a recent Estate sale purchase...this is what I think may be a Vintage Murano Art Glass...although there is a slight dent above the mouth...it looks like it happened during the time it was made....its approx.8.5 in length x 9in ht....its in great condition with no apparent damage...it does have the millefiori design....but I'm not entirely sure if it is truly a Murano.... if someone knows, please feel free to share your thoughts
