Seahorse on a Frogfish

At the very end of an amazing night dive on Mafia Island in Tanzania arranged by David of Mafia Island Diving. My dive buddy Anna Madrugo found a Frogfish and called me over. After taking a few images of the Frogfish Anna started making excited noises and pointing and then I saw it , a juvenile Seahorse hooked around the Frogfishes right pelvic fin. A Seahorse on a Frogfish, not something you might expect to see !
