ok so i was browsing around walmart and somehow wound up in the crafts section. i started looking at the fake plants and got to wondering if i could use them in my tank? if so i have a million ideas of how to plant the tank. what im wondering is if its safe to use those? not the flowers or things with glitter, just some ivy and another plant that looks like beach grass. any opinions and advice would be great! i hope i can use them bc i have some awesome ideas!
