Tano revealed that when he caught the fish, he wrapped it inside his t-shirt. What he didn’t realize is that the print on his shirt reacted with the fish’s skin, causing the print to ‘transfer’ unto to the creature.
No wonder the prints were so well-defined and intricate!
To prove that he was telling the truth and that there was no magic to the tattooed fish’s markings, Tano showed his t-shirt to ABS-CBN News. True enough, the print on the shirt matched the one on the fish!
Whew! Mystery solved!
