I'm trying to find some high reolution images of very popular fish this to enlarge them to 1 x 1meter or even more!
Who can deliver me some?

Check stock photography agencies. I doubt you'll get anything of that quality for free.
For digital images, you'll want a very high quality resampling program to upsize to something that big. PHotoshop's bicubic is pretty good, but works best if you "stairstep" (increase in 5-10% increments to the size you want) the increase instead of just doing it all at once.
The best quality resampling program is probably Genuine Fractals.

Dear liarian thanks, but about the Photoshop’s bicubic is this part of Photoshop or a supplementary program? What would be necessary of quality for an image to enlarge to 1 x 1 meter? I do have a digital Sony 737, 5 Mpixels but can not get clear images of fish in the aquarium! I this, because I do not use a polarization filter? Or do I need no filter at all to make clear images trough the glass??

Photoshop's bicubic interpolation is its best method for resizing images (its the default as well).
5MP is, in my opinion, nowhere near enough to get anything decent a 1mX1m size. Illusion's pic is nice and clear, however, and could perhaps be blown up to that size and look decent.
BTW, dpi is meaningless for anything except print. Screen resolution is almost always 72dpi for digital, and when you're taking a digital image and converting it to print, typically you set the final print size and dpi you want, then resample the image so it fits that format. (Typically 200-300dpi).
For an example, to take Illusion's picture and make it 180dpi @1mX1m size, cropping the sizes off to fit the 1:1 aspect ratio, you'd end up with a digital image at around 7020x7020, or 49MP. That's about an 8x upsample.
If you're interested in seeing what I mean, and somebody is willing to give me a good original image (prefereable in TIFF format), I'll upsample it to the size you're talking about. I'm in the process of moving, so all my archived images are packed in a box somewhere. =)

Oh, I missed the question about clear pictures. I would not use a filter, make sure as much ambient light as possible is off, and use a tripod. Beyond that, its a matter of playing around with your individual camera to get it to work.
