Does it matter what kind of live rock you buy? I know Fiji is popular in most places, but I have seen others (Tongan, Carribean, Premium, Ultra) and wondering what is best to get.
I think the "best" is just a matter of opinion. As some have already said, there can be differences in porousness/weight, life on the rock, etc. When it comes down to it, you and your octo have to live with it, so you should try picking rock that you ultimately like. When it comes to whole reef tanks, I'd say it's pretty important to pick rock that has a lot of life on it [which, of course, tends to be more expensive], but a lot of LFS will carry less expensive rock that doesn't have a lot of coralline or other things on it....but it's still considered live.
When picking my rock [and I bought a ton of it for Beaker, my
O. Aculeatus] I chose a combo of plate rock and branching, plus some "premium" rock in hopes of getting the coralline to spread....rocks that could easily make sturdy caves for him to hang out in and feel safe when he didn't feel like being in his den.
Well, the choice is ultimately yours! good luck!
