I have a big lava rock in my tank in the center and it has nice golfball
sized holes in the top. I want to put one of my anubias barteri/nana
(whichever is the small one) in the hole but each time I get it in there it
gets knocked out by fish within a day. What would you suggest is the best
way to secure it?
