I just couldn't get the right side to look good for my eyes with any rocks. Tried a group of small ones and it just didn't look right. I decided to leave it open.
My LFS was supposed to get a "big" shipment of plants in today. Unfortunately, they only had like 20 random crypts. Not normally like them...Just threw some extra plants from the breeder in for now. Going to Chicago this weekend, but I'll grab some more plants when I get back home!
Sorry for the bad pictures! Using the iPhone.
