If this is one of the recent captures then this seems likely to be the male (going only off the drooping dorsal fin).
This poor guy hasn’t even been put in a marine park yet and already captivity is affecting him (collapsing dorsal fin).
Why can’t people get it through their thick skulls that these animals are destroyed in captivity? They just cannot thrive there so just stop it. Leave them be in the oceans with their families where they were intended to be.
