if you wanna get nice shots, i don't think 1.3 is very good.
you can get a 2.0 megapixel Nikon for about $180 now.
you can get a 3.0 mp Nikon for about $300.
those pictures will handle cropping and enlarging much better than a 1.3 mp photo.
if you're lookin' to take pics of your tank, look for a camera with macro mode too. something that has a focus depth of 4cm or less. that makes for great close ups.

if you are strictly posting pics online, then 1.2 is plenty, if you want to print photos bigger then 5x7 then no. But to post online, heack it more then enough. here is a little break down on MP and what does what
To figure out what size prints you can make from today's digital cameras, you have to first break down the pixel measurements. For example, a 4.1-megapixel camera works out to a picture with dimensions of 1704 x 2272 pixels at its highest resolution; a 3.34 megapixel camera works out to 1536 x 2048 pixels;and, a 2.24 megapixel camera works out to approximately 1280 x 1600 pixels.
For a reasonable quality print you need approximately 150 pixels per inch of resolution (we'll call this medium quality), while for professional quality prints you need at least double that. For simplicity's sake, pick either the long or short dimension of the print/camera resolution and work with that one. For this instance we'll use the long edge of the print. Let's work through a couple of examples:
2.24 Megapixels
Maximum print size (medium quality) for a 2.24 megapixel camera: 1600 divided by 150 = 10.7." Using this example, you could get a medium quality print of up to about 10 inches (so you could get a medium quality 8"x10")
Maximum pro quality print size would be 1600 divided by 300 = 5.3". In this case, you'd be able to get a pro quality print at 3.5" x 5".
3.34 Megapixels
Maximum print size (medium quality) for a 3.34 megapixel camera: 2048 divided by 150 = 13.65", so you'd be able to get a medium quality print of close to 11" x 14".
Maximum pro quality print size would be 2048 divided by 300 = 6.8." In this case, you'd be able to get a pro quality print at 5" x 7."
4.1 Megapixels
Maximum print size (medium quality) for a 4.1 megapixel camera: 2272 divided by 150 = 15.14", so you'd be able to get a medium quality print of close to 11" x 14" with the option of cropping an inch around the edges to emphasize your subject some more.
Maximum pro quality print size would be 2272 divided by 300 = 7.57." In this case, you'd be able to get a pro quality print at 8" x 10" with a border.
Keep in mind that these guidelines are not absolute! Your lens, lighting, CCD quality and method of printing all play a part in the final results. Also, the resolutions quoted are based on optical resolution and not interpolated (upsampled) resolution. The formulas can be applied to cameras of any resolution, or you can work the formula backwards to find out how many megapixels are required to get the image quality you require at the size you will be printing. Good luck!
