Yeah, it's a bit of a less, and I have less ferns there now. I'm thinking of removing some of the dwarf sag at the front for something else that's shorter to give it a better contrast, but given tank conditions I don't think I can support much else in terms of foreground plants.
So will be background plants now. Any suggestions? I do agree that it is too bare (hardscape) on that one side and it will be need some plants to help bolster it.
