I don't know how I should finish the scape on my 29 gallon. I am not sure if I should leave the center part of the tank open and let it just have some crypts, or let some plants grow in the center. Here is a pic of the tank with a crinum natans plant and some red tiger lotus just growing out. What do you think? Should I let them grow bigger and taller? Or pull them out and let some crypts grow in for a crypt carpet? Thanks
