I'm looking for some advise. I decided to start up another tank, had an empty 20G. I figured fish and inverts, I don't want to spend the money on lighting for coral in this one. I have about 20lbs of live rock, I'm sure I'll add some when I find more I like. I used dry aragonite sand, a little coarser than my other two tanks. I think it'd be neat to have some type of digger, someting that would make caves or something like that. Any recommendations? FYI: not ready cycled yet so just in the thinking process.
