But you would not shoot corals at 400mm.. it's better with a smaller lens from closer or a macro lens. My 400mm focus at 12 feet...so I would not even be able to take a photo of the aquarium without hitting the wall.
I did tons of macro of insects and never used a tripod and with the aquarium and either LED or MH, the light is so strong that getting the speed to get sharp photos is not a problem. If there is blur from the motion of the person, usually there is not enough speed and the coral will be blurred if it is moving, at least the polyps will.
If you use a slow shutter, you might get blurry pic tripod or not.

So the only way to avoid camera shake is to use a tripod
