Are you sure it does the same stuff as the vortex? because I know someone who designs LED's as well and he said no matter what, these are better than his. and his are cheaper than these.
have you checked out Reef Tech LED? They have some insane fixtures. The Prometheus fixture by them is about 1300 a piece with the wireless internet setup so you can program how you want everything to run on your computer. Prometheus
That tank looks to small for a vlamingi tang... Did you know those yellow finned fish are brackish water? I didn't know they could survive in a reef environment.
If you were, you might, but I am, so im not making a predator tank. And I dont want a predator tank. There are about 4 big fish there, a couple of others which I have in my 60g (the two pairs) And I want a school of anthias. I might get one more big fish and thats it.
