I can't tell if this rock is live or not. Any help would be appreciated
The one on the bottom is the one I don't know
Is that real coraline algae on it or painted on? How long has it been in the tank? If its been in more than a day its live to an extent as bacteria has attached to it. How penetrated it is depends on how long its been there.
It's been 6 months
Yes I'd consider that live rock then.
