30 gallon now a bit tight for an octo

[rudy]

In anticipation of my ocotopus I have been adding corals to my 30 gallon oceanic.

I am kind of liking the coral in there. If I was to keep just corals with a small Ciliatis Mantis shrimp in there could I get away with no skimmer with regular water changes. I may change my plans and keep my octopus in a 50 gallon at work with a couple of mushroom corals so I would need the skimmer there.


I was originally going to keep a 15 nano at my office with the mantis, but this kind of looks nice..... so now I am thinking twice.
