The huge fish can be intimidating if that’s your first time being with them. However, they have no teeth, move slow & are gentle fish. You can get away from them easily. If they are on your back, you’ll be just being pushed away. You can feel the streaming water pushing you before their fins touching you.
I had a blast just hanging in the water column and enjoying the show. Dive operator would tie a rope on each corners of the bagan, where you can just hang on to it and enjoy the show.
What you don’t want to do is to chase them around, up & down the water column in order to get a good shot or footage. In the first 10m (30 ft) depth, the hydraulic pressure changes from 1 to 2 atmosphere. That’s a huge pressure change. If you move up & down too much, you can stress up your eardrums to the point of swelling Eustachian tube and retaining fluid in cavity behind your eardrums (Middle ears) and it would take a week to drain the fluid out of your middle ear.
Some of us just hang on the ropes & stick with U dive profile. Some of us that have good buoyancy control, use V dive profile starting few minutes just below the surface, as this dive usually starts very early (7am) with limited sun light, but good visibility, then went down to 5m to see the Whaleshark coming from the depth to the surface, then went down to 10-15m to see the dolphins and sailfish that mostly stay at depth and slowly ascend to 5m, where the morning sunlight was brighter, until we have enough or ran out of gas, as shown in the video. I think most of us dove there close to 2 hours.
