I have removed the hornwort which I think helps already, it was very distracting. I added some river stones and rocks, not sure if I like them or not, but I had them and thought I'd try them. I have decided to remove the gravel and add some more fluorite. I really want to avoid a copycat tank of my 10gal, and do something different.
Plants I'm thinking of adding, some swords, vals, water sprite, crypts. My other tank is very 'bushy'. I'm thinking more stemy/leafy for this one. But I definitely need more, regardless!
