1 or 2 more rocks,same variety and smaller in size first one maybe a 3rd in size and second smaller again.
from my experience with 1 11w arcadia light over one of these tanks you may struggle with the likes of glosso....it will grow upwards. but then more light means co2.
maybe try a crypt iwagumi?...parva in the foreground? wendeti green midground and becketi behind that?......would look different.and would work
