I have some natural colored fine gravel I had bought for a future community tank, but i decided to turn my 20g into a planted betta tank..hes is a plakat so im not worried about tail damage et...but will fine gravel be okay for plants or will I need to use a different type of substrate. I also plan to incorperate shrimp at some point.
I have gravel in all 3 of my tanks, pea gravel in the 46g & a little larger in the 2 10g tanks, my p,ants are doing great. I think to some degree the gravel allows better circulation around the roots but that could just be my crazy thinking. I add Flourish & excel weekly with my water changes.
