ah, looked up the specs, it's hard to take fish pics without optical zoom(real zoom on the lens), the pics you took look like you maxed out the digital zoom(just a magnifier - cheap ineffective trick), digital zoom really degrades the image quality, try not using any zoom and using the flash, angle the camera so you don't get hit in the face with the flash, just go closer to the fish slowly to make up for the absence of zoom, don't know if you have shutter speed and flash output control on the camera, if you do you can play with those too
