My tank is rather blah right now because I want more decent sized fish in the tank or rather, a center-piece. I am on a pretty tight budget so I was thinking about going with 4-5 dwarf gourami because they have a hint of red to add flare. I had thought about silver dollars but after some research, I realized that I'd have an unplanted tank the next morning haha. At the moment I have 16 neons and 6 amano shrimps and 2 otocinclus. What would be a great center-piece at a rather low price?
