I have had these tangs for almost two years. I bought three and lost one right away because it jumped out. I was very successful at keeping them with a purple and a yellow tang. When I bought these fish I did not have a QT tank. I buy all my fish from a guy who maintains aquariums for a living, not an LFS.
This fall our friend from Chicago wanted to get rid of his 120. We drove to Chicago from Mpls. one day and back the next with his setup. I had a 29 bow that I set up for the fish. I hooked up a pump from my sump to the 29. An overflow box brought the water back to the sump. I also ran a 350 magnum in it with carbon. His fish included:
Vlemengi Tang, Flame Angel, Damsel, 3 Perula Clowns, Regal Tang, PJ Cardinal, Flame Hawk, Coral Hawk, 2 Dotty Backs, Coral Banded Shrimp and a Spiney Urchin. I also added about 50 lbs of liverock and some misc. coral to my 125 tank. I was very careful to do water changes on a regular basis and do frequent water tests. I did not lose any fish from this trip and did not have any disease. I sold the Vlemengi and the Flame. When the 120 was cycled I moved most of the fish to the new tank. I added the Regal to the 125 with my other tangs. They all did fine for a couple of months.
That gives you a little background on my tanks.
I tested my water yesterday.
Salinity 1.024
pH 8.2
Alk 3.0
CA 370
nitrates 0
nitrites 0
phosphates 0
ammonia 0
As for feeding I feed flake (spirulina) and frozen food. I have a small variety of frozen and will feed some containing fish and others containing plants. I feed once a day. I also have DT's phytoplankton for corals.
I have a UV sterilizer but I shut it off on this tank. When I moved the fish out of the 29 I turned it into a refugium. I have grape caulerpa growing in it. I have not added anything to this tank if anything I have removed it. I had too many anemones. Now I am down to one rose and a very small bubble tip.
Did I miss anything? Temp stays around 80-82.
