faster shutter speed

As said bafore faster shutter seed, though you would need to use a bigger aperture (smaller number) to compensate for the decrease in light. You might also need a higher ISO if your fastest shutter speed does not give enough light at the widest aperture of your lens.
Wastch out for the limited Deapth of field which will then need careful focusing and no recomposing after your camera has focused.
a Tripod would also decrease teh part of the blurriness that is cuased by handshake.

While those are all good suggestions, this particular example's blurriness is missed focus not camera shake. The liverock is where the camera focused, not on the fish like you wanted it to. What camera are you using? The reason I ask is the advice will be a little different if it's a point and shoot.

correct me if im wrong, but the clip and the still parts of the algea sheet are in focus, and they appear to be closer to the glass than the tang, and the rock behind it also. If thats the case, than it would be shutter speed, if not, than its a focus issue.

I agree with the idea of the missed focus. As yes indeed the rock is much sharper than the fish. Eventhough the rock is pointing frontwards so might be just under the fish, at this shallow DOF aperture (2.9 as per EXIF data), if the rock is sharp the fish is not in focus. Sorry can't find the words to explain it but at such shallow DOF the area in focus will move in a semi circle the clip is a bit more in focu than the fish, still not sharp which leads me to think that at that height the focus is somewhere in between the fish and the clip. go lower and the focus goes tot he back ie tot he rocks. it all depends of the camera position.
So in short it is a missed focus.
BUT
Still looking at he EXIF data it was shot at 1/15 2.9 aperture and at a weird focal length of 5.8 mm it's an plympus camera that the model does not show in the EXIF and there is one field stating macro 2
I presume it's some macro mode in an Olympus P&S
ISO is still at 100
so you have reached your widest aperture still shutter speed is too slow. I go back to my comment above to increase your ISO hoping it will increase your shutter speed a bit.
one other thing to think about is that with the very limited DOF combined to shutter lag in point and shoot cameras, the fish will most probably move out of focus before the shot is actually taken. this can be dealt with by using a tripod, focusing on an area and then waiting for the fish to go in this area and stay still.
other option would be to use a flash but then you need to take care about the reflections, shoting pointed down to avoid reflections, that in turn causes more distortion in the glass.
Increasing the tank lighting can help a bit but still not enough.
In the end that just justifies moving to a DSLR with a flash that's farther away of the lens or maybe an off camera flash.
Enjoy.

the shutter speed is too slow, see how there appears to be two dorsal(i think thats what they are called, the top fin) the fish moved and you now have 2 fins lol. and i do agree with the missed focus

Increase your shutter speed or move the camera with the tang, keeping the AF point on the same section of the fish for the entire frame. Like golf, tennis, or any other scenario...follow through.
