live plants are easy as pie as long as you KNOW what plant you are getting. i have a 75 gallon, no co2, no fertilizer, regular gravel and it is fully planted. that being said all i have is java fern which is indestructable, Anubias, also indestructable, and hornwort, indestructable. and, none of those plants even has to be rooted, so i can gravel vac all day with no ill effects. oh, also some bannana plants too. it looks great, helps with filtration, looks so much nicer than silk plants and really makes things look alive. so if i were you i would get the easy plants, java fern, java moss, anubias, hornwort. im sure there are other super super easy plants but those are what i have. oh, and i literally give them no special care whatsoever, i treat them like plastic plants and they still grow great. ive even totally planted other tanks just from propagation. plants do not have to be hard at all
