i actually really like the one plant.. i feel like you should put just a single rock next to it and let that bad grow.. maybe rake the sand too lol have a simple zen tank
really do it man! one Nice Sharp edged rock that is big like a tooth! and then rake the sand! get rid off all fish and have one single ghost shrimp haha!
You can go to your local sandblasting company and ask them for some of their used sand. They are more than happy to get rid of it and its nice and white looking just like the real stuff, plus its free.
