    I can only tell you about 6500k and 10,000k. I was not a fan of the 6500k's because of the yellowness factor. I liked the 10k's as they were a crisp white color. I'm guessing I missed a number of intermediate posts. I'm gonna go searching for them now to see if I have any input.

    Awesome aquascaping!!!

    I'm worried about the tang though. The tank is VERY clean of algae---cleaner than mine :) . Do you have any Nori or nori clips? I cannot see the tang from the front so maybe my worries are unfounded. Please don't think I'm being critical at all---because I'm not----it's more of a concern. (The thickness under the dorsal fin is more telling than stomach size).

    Here's my concern. Tangs are grazers and do awesome jobs of removing nuisance algaes. However, once they are done grazing, they need supplemental plant material like Nori.

    Like I said, I may be overreacting because I can't see your tang from the front. I just wanted to throw this out there just in case.

    i supplement the tang with feedings every 2 days with Marine green 40(40% veggie flake food) also he easts very well when i feed them frozen mysis shrimp,frozen brine shrimp, brine shrimp formula flake, frozen krill, and regular marine flakes, the tang is prbrably the most aggressive feeder in the tank, hopefully that is enough? if not please tell me, i would hate to think he isnt getting enough food!! he is my fav fish! color is awesome and behavior is intriguing.. heres a better puc of the tang

    Yeah the coraline growth is normal.

    Nice tang! Looks good to me, although he is going to make any new additions pay - very territorial - be sure to move rock if you add any more fish. Tangs are recommended to be the last fish you add for that reason.

    to be honest, he was my second fish to add, he is VERY passive, and not relly territorial, as of yet, i had added 1 gramma and a fiji damsel, he left them alone, but the three spot damsel chased them around really bad, i eventually took them out, and back to to lfs, and have resolved to only getting sih similar or larger then the three spot, really i have seen absolutley no aggressive nature from this tang, but thx for the tip!

    The tang looks MUCH better in that pic. It's storing fat under it's dorsal fin. The important thing to remember about tangs is that they are grazers and like to be eating whenever they want. That's why a lot of people will put a piece of nori in their tank if there is no algae for them to graze on.

    Craig Manoukian has a number of tangs so hopefully he will see this post and throw in his 2 cents.

    Regarding the coralline issue. That means that your tank chemistry is well balanced. Although some of it will likely bleach once you add higher lighting. Some species are more light tolerant than others. As long as the chemistry stays balanced, you will start growing coralline again. Also, everytime you scrape it, you are seeding even more coralline as the spores will float somewhere else and start growing.

    Tangs need a minimum of 48" in lateral swim room and 75 gallons as they can become quite large in a home aquarium.  As for the algae, the fine green algae that accumulates on the glass will be of no value to this tang.  Macro algae is what is needed as you can see by the shape of its mouth.  Caulerpa and turf algae are favorites for them to nibble and pick at.  You will need to supplement the diet with Nori seaweed or other suitable macro algae replacements.  

    A Yellow Eyed Kole tang is a master it cleaning the algae off of the glass.  HTH
