Until today never heard of living color reefs but shoulda expected it and after lots of searching didn't find the same tank but it was similar sorry wouldn't let me post link but was built by this company

If you have a deep pocketbook they'll build it

Yea they're a pretty penny. But IMO no fun cause its all fake, nothing grows or needs attention. I think I'd find it boring personally, that being said they are great for people with minimal maintenance time.
