I have one myself. Cool fish but mine hides alot. Hes getting better but still hides. I would get a neon goby but i think my big pink spotted watchman goby would eat him.
good chiller.
ask:
age?
use age?
dual or single controller?
Just so u know the chiller will need to be plumb out side so be ready to put a hole in a wall or lift up a window.
