Running a small submersible pump on battery power.
I have a project that requires a small water pump to be ran on some kind of battery power. I will be using a pump like this: Tetra Pond Statuary Pumps: Pond Water Pumps
How would I go about either modifying the cord or plugging into some kind of device/battery to make it work. It will only have to be able to run for about 4 to 5 hours. The pump will be in small glass bowl and the battery and cords would be hidden on the outside by some kind of decoration. Any suggestions would be appreciated.

If you search around there are plenty of 12 volt pumps that will run directly from a car battery. Otherwise to use a 120V pump from a battery you will need to get an inverter. These are a common item that plugs in to the cigarette lighter in a car.

I should have been more specific. There's no way I can hide a car battery on a table. I was looking for something way smaller. As for an inverter, I can't really bring a car inside.

That pump is 120 volt 60 Hz AC. There are 120V battery backups available.
Which pump size do you want to use? Your link shows several sizes and wattages.

I need to know the wattage of the pump.
HERE is a 120V UPS (Uninterruptible Power Supply) that will run 120V, six watts for about five hours.
Height 5.52inches, Width 9.98inches, Depth 4.13inches
You're not going to find a UPS much smaller than that.
APC makes an excellent UPS

Use a little pump like this:
https://www.amazon.com/Yeeco-Electri...volt+pond+pump
You can run it off 4 D cells wired in series and it should run for at least 5 hours. Might be able to get away with C cells.

So if I get something like this: https://www.superbrightleds.com/more...Specifications It should have enough power and will last for the required time?

If you get the D Cell version yes. Hard to tell if the connectors will mate as they don't give a lot of information, but it looks like they will.
