Can I use Unity3D to make a virtual aquarium game ?

I was wondering if Unity3D can help me create a 2D real-time aquarium simulation game exactly like fishville from Facebook, where you have to feed, buy and sell fish (I would like to make a similar game but add breeding, a male/female version of every fish and many more options…) Is that possible with Unity3D ?

That would indeed be possible with Unity3D. You are going to have to learn some programming though but there are plenty of good resources for Unity around the web.

I made an aquarium.

I have not updated the website in a while, but the tank
can do a billion things if buisness is done.
