Bought an established nano off CL, the coral was the only thing in it.
Checked salinity, 1.015.
Going to do some water changes over the next couple of days to bring it up.
Clean the filters and put something in it.
I was tempted to go all in on Kenya tree. I have one that is coming back from the dead. I cut it at the base of the stump and the new growth looks almost exactly like what is pictured. But on second thought the extended polyps, texture of the cap and the base look a lot like a toadstool.
