i hope this helpsAhhh yeah I see, it can be so hard gauging issues like that from a photo. My tank has similar situations where moving aspects of it even slightly would be impossible woithout a complete re-work.
I think it is going to look great as is especially once that Bylax japonica gets established. I really love the 'grass-like' looking plants.
It would be great to see a photo from the front but lower too, to help gauge the height differences of the rock. Just purely out of interest
What are you plans in the tank with regards to livestock? Is this going to be a shrimp tank?
