I bought a bunch of bundles of amazon swords today, now there all in the tank, and all the plastic plants are gone. It looks pretty good, except that the plants have a couple nasty looking leavs on them. Should i rip these leaves off? or leave them on and wait for them too fall off? Is there anything i should be concerned with now that i ahve real plants? I leave my lights on for around 6-9 hours a day.
