The next step is making sure that your filter can handle the task. Also, add new gravel to make your tank look fresh and natural. Now put in some new furniture. This is where you can have all the fun you want. In this case, the perfect tank additions will have the biggest impact. Take into consideration how much into your fish theme you are willing to go. To create extreme aquariums, just ensure that all visual elements of design are satisfied; colour, depth, balance, interest and focal point. Now step back and enjoy your masterpiece.
