Forgive the spelling, but I am converting my newly cycled tank from plastic plants (ugly) to real plants. I am considering ordering 5 bunches (or more) of anacharis for my 55 from aquariumplantscom. Do I simply plant the bunches in my substrate, or try to split them up? I realize they grow fast. I will add other varieties later. Using a Current Satellite Plus LED, 18 inches above substrate. Should I use a liquid fertilizer as well? Thanks!
