The ocean doesn't generate waves with propeller pumps though, sucking in water and spitting it out. Whilst yes the ocean waves produce far more current it's still a different type of current to what's in our tanks, when you think about the more natural waves in the ocean. Whilst it's very possible and likely this little guy could of got stuck on a rock or get eaten alive in the wild anyway. I think from memory survival rates in the wild are extremely low for juvenile fish, I still think you increase the odds using something less aggressive until they are bigger(just look at breeding tanks). And if I remember correctly juvenile fish hang out in shallow lagoons or mangroves, less turbulent until they are older. Some one will correct me if I'm wrong, I'm sure
A big fish getting stuck in a wave maker I would argue yes a health issue. But that's the good thing about this hobby, still lots of unknowns and lots to debate :)
