Hey everyone! So I bought this Fluval Evo 13.5 secondhand on Saturday and the live rock that came with the tank had some mystery coral. The tank had been up and running for 2 years prior to my purchasing of it, so whatever coral this is has been residing in this tank for a while. Unfortunately all my photos are quite poor as it has been closed up ever since I reset the tank up in my living room. I really would like to keep this coral alive if possible, but I am a beginner to reefing, so Im most definitely out of my depth.
