Wow what a nice change from the massive, sps dominated tanks that usually get the honor of Tank of the Month.
Beautiful little 20 gallon tank Cameron. Very clean setup.
I noticed you mentioned having 3
S. magnificas. The fact that you have 3 in a 20g means you love them as much as me.

I was wondering how long they have been in your tank. Coincidentally, I had 3 myself in my first reef tank some 10 years ago. None made it to the one year mark sadly, although one
almost did (it survived 10-11 months if I remember correctly).
Anyway, congratulations!! And again, great job, and beautiful tank.
