So, I have a 37g tank right now. I have a couple of large Anubias that I split and are doing well, and a couple Amazon swords and some wisteria. They are all planted into a moderately small size of gravel. I was just wondering if it was more productive to just plant them and let their roots hold them in, or if it would be better to get some of those small black plastic pots and plant them with those, based of the size of the gravel. I have never really been sure if they could really hold themselves into the gravel if needed, or if it was totally ok. Just wondering here if I need to change something up or if it's all good. And thoughts would be appreciated. Thanks.
