Hi! Well it depends on what you want it to look like? I personally love a natural theme. A really cool tank would have white sand, whit half of the tank heavily planted. And the other half with a cave and 1 small Anubis., and of course, some driftwood! Do you know about cycling your tank? If not someone will give you a link to the guide(I can't find it) and help you there. What fish do you want in it?
Lastly,
Welcome to the fourm, have fun!
