That's actually the made-up definition of specific power I gave and not your's. So, I'll reiterate - Aquaman is not the only character that can talk to marine life. There's Aqualad, Lagoon Boy, and Animal Man on the DC side, and Namor on the Marvel side, to only name a few. So, by that definition, talking to fish is not Aquaman's specific power. In fact, he has no specific power, because there is no super power unique to one character.
