How much Space behind rock in tank?

[tunicata]

Hey...
So, currently, I have about...3-4 inches at least behind all of the rocks in my tank before you hit the back wall.

I did this because a lot of readings say to leave space for detritus removal, fish to roam freely, nice visual, etc. Now, yes, I can see that my sand is pretty clean back there (I have a tiger cuke that has cloned itself 4 times ). Also, if a frag falls or i want to spy on fish, I can easily get/do that.


However, most tanks I see have little to no room behind there- the rocks are pretty much 1" or less to the back wall.

I am thinking of rescaping and am thinking about moving the rocks 2 inches back to give me more room for the floor.

This is a standard 120 non-reef ready.

What do you think? How is your tank scaped?
Any problems?

I have at least 4" to back wall, I touch a powerless on the one side to push all detritus to the one IDE for easier maintenance. I don't have sand in dt though so I guess it's slightly different. If working for you I'd leave alone unless you want to rescape the rock. My clowns occasionally go and hang out in rear of tank then Come back up font

Yea, it has a lot of pros to it definitely. I would only move the rocks back a bit becausemy clowns make gigantic holes in the sand around lower ledges .

I figure if I push the rocks back, I can raise the height of the ledges (push pvc pipe under them) so that when the clowns throw sand around, it's less likely to smother my coral.

i've lost so many coral due to their baby making moves.

Also, I just want more floor space for LPS.
