Would love to give you a lesson on Photography but unfortunately time is short when you are on call all the time as a press snapper. Anyway try this, set your iso to 400, now you dont mention what lens you are using but use Av mode, this will let your camera decide what your shutter speed will be, put the camera on a tripod as I'm kinda sure you might get some blur if you hand hold. For faster movement use a lower Aperture like 5.6 for example. Some more expensive lenses will let you go to 2.8 but they are pricey. camera will decide shutter speed, now at 400 iso you should be ok at 5.6 to photograph fish and moving animals but then again I dont know what your shutter speed is, if it is still too slow try 800 iso as a last resort also once you get a feel of the fishes movements its easier to ready yourself to fire the shutter. Now for corals and things that arent moving too quick, use a tripod and set a higher aperture like f11-16, your shutter speed is going to be way slow but your depth of field will be greater allowing for more of the coral in the foreground and more in the background to be in focus. Very important that you have a tripod for this, finally use the self timer once you have your shot set up as you may cause movement when firing the shutter manually. Set the focus, press the shutter release and allow the camera to do its 10 sec self timer delay and fire..voila, picture should be fine. Now with the advent of Digital you can experiment with different things, trial and error has become a lot cheaper and practice makes perfect. I have been a photographer for 11 years and the learning never stops....
