ok, i've got some swordtail plants (along w/ annachris, moneywort, myrio, and some huge leafed plant that the pet store sold mistakenly as swordtail) in my tropical aquarium. they're doing well but when i go to clean the gravel i'm always afraid of disrupting the root system.
i've seen a couple pics of people's tanks on here and they've got plants growing out of the little clay pots. i think that'd be a neat look in my aquarium, so i was wondering how i would go about doing that. obviously you don't put soil in there, but what do you use to hold the plant into the pot? is there anything else i'd need to do or can do to help the plants w/out harming my fish? and would any small clay pot work or should i get something specific.
thanks for the help.
