The Bottomless Fish Pond features an interactive fish pond that actually allows you to feed the fish with your computer mouse and also allows you to change the pond background color to the color of your preference after the initial installation with a few mouse clicks. The default color of the pond is light black (Bottomless Pond) however you can change it to Light Blue, Dark Blue, Red, Pink, Green and many other color if you desired. This is a-one-time that you can actually enjoy feeding the fish without worrying about running out of fish food, or over feeding, no mess to clean up. If the water in the pond is dirty, don't change the water-just change the color instead. You will be able to feed the fish right on your computer screen for fun. In case you didn’t know there is fish food in the mouse. Don’t believe it. Try it. Make sure you will have time to feed them otherwise don't get them, because they are always hungry and looking around to feed even under lily pad. You can feed them to your heart desired like a good pet owner would. You will never run out of fish food so don't worry making a run to pets store on the weekend. Just feed them the fish food that is coming out from the mouse because they are used to it. They are very, very cute indeed; cute enough to attraction audiences of all ages, but please don't quarrel, just take turn to feed. They will run to where you put the food, if not they will roaming about endlessly. Have fun! But children please make sure your home work is done first! It is fun for the whole family.
