As you can see from the first screenshot, the top card on the table is 7 high, there are two spades and two connected cards. The perfect hand for a fish (or two).
The second screenshot, both players have shown their hands as they are both all in.
The third screenshot shows the turn/river and despite the 72 off hitting trips, he loses to a straight.
I hope these screenies assist in some way to recognize a perfect fish flop when you see one.
