I am using D70s with F1.8 50mm lens..i need some advice on focusing...
I am shooting asian arowanas...
most of my shots will appear part of the fish focused but other part out of focus..
my focus mode is "Dynamic"
can anyone advice how can i improve my focusing
aim for the eye. the problem is probably a large aperture size (small f-number). you can use a smaller aperture, maybe f13 or so and you should get more DOF.

Use single area focus, not dynamic, aim for the eye. And respect the minimum distance of which the lense can focus. 0.43cm or so.
If you have enough light, close the aparture (smaller aparture, higher f/number.)

single focus area okie will note that...wat about center weight wat setting or it doesn't matter...
mine is a fix lens F1.8 i could try using the stock lens with bigger aperture but however photos always appear underexposed n very dark ...cos i do not take with flash..
I'd stick with the 50mm f/1.8 if you're limited by the lighting. It has a higher max aperture than the kit lens and will let in more light than what the kit lens is capable of. Bump ISO if you have to.
Stop down like the others have said and see how far you can push it while still maintaining a decent amount of shutter speed.
BTW, I just pulled out my 50mm and it doesn't look very good in terms of shutter speed with available lighting. Here's a few shots to illustrate. All three shot at ISO 500 and have not been run through noise reduction. Also, excuse the messiness of these shots...only for testing purposes.
Both of these are at f/1.8. Shutter speed on first one is 1/100 and the second is 1/125 since the fish are closer to the light.

...and finally one at f/2.2. Shutter speed dropped to 1/60 on this shot.
