I had a 15 and a 29 nano reef for awhile....until I put both of those tanks together into a 50 last March.
Here's some pics of the two......
the 15
the 29
I've had the 15 sitting around empty ever since closing it down...but I've found a new interest and so needed to set up that 15 again...
My new interests...
and the beginnings of a new 15 nano for them......
absolutely beautiful fish !
Oh....they're purple firefish...........I'm hoping that I have a male/female pair, but will have to wait and see.
