You could do just a community tank with tropical fish ( loaches, Cory catfish, mollies, platies, tetras, etc... ) and then do a puffer tank separately later on with a pair of figure 8 puffers , great idea first puffers to care for when your first starting out . I did that when I started out cause I wanted dojo loaches cause there one of my favorite fishes having them when I was growing up. So I started with a community tank and got a another tank for puffers as I got a little more knowledge with the fish hobby again. Also as the homemade decor goes - here something I just made with aquarium sealant and river rocks.
