Save your money!!!! Fish do not care what is in the tank with them. The best stuff you can get for your tank no matter what kind of fish you have are rocks and/or live plants. You will spend $$$$ on decorations that don't look that great. Clay pots are great and after awhile they will have a ton of algae cover and blend in very nice. I spent 25 bucks on clay pots and moss for my 125g new world tank and it looked great. You don't have to spend a lot to make your tanks look amazing. Just a couple of ideas for you. Good luck
