I have a few Temple plants and hygrophila blue's in my tank. Right now I have them all planted in the substrate, but before I did that I kind of let them just sit in the tank unplanted for a few days before I decided where I wanted to put everything. I've come to realize I kind of like the look of the plants floating freely, is there anything wrong with doing this permanently? The plants are all doing really well and have a ton of roots growing out all over the place, most of them need to be trimmed actually. Are there any drawbacks to doing this?
