I have been looking to get AT for a while and finally picked one up 2 days ago. I had a 40 gallon qt set up and put him in there but after finding this primer, I decided to take a chance and DT him. I have a 180 gallon 6 foot tank with 3 other tangs in there, a small yellow, medium sized powder blue and a desjardini. Until I put the AT in there, you can imagine that pow blue was king. What I did is go to HD and buy 12$ light diffuser cover (the one that has little squares), cut it to proportion and ward off half the tank. I put AT in the half without other tangs and kept him there all night solo. The fish noticed eachother and ofcourse PBT took a special interest in him. As a note, the AT is bigger than BTW by about 1.5 inches.
Well this morning i removed the divider and ofcourse PBT went for AT as soon as he saw the highway to heaven open up. I knew that this is a possibility which is why i made the divider. After about 5-10 mins, AT went into the rockwork on "his" side of the tank and pbt is occasionally cruising past the cave but does not go in there. As a matter of fact, AT twiches at PBT from his cave in a gangsta WHAAAA style and PBT twitches away.
I hope this works out as I did not want to see a nice specimen waste away in a QT. I hope the other tangs teach him to eat since he really wasnt eating in QT (altho he was only there for a day and 2 days at the importers). My tank was previously ich free - I hypod the other tangs incluiding PBT without a problem and they were rock solid *knock on wood*. I have to go to work so I hope I come back and everyone is more relaxed. Those are the only 4 fish in the tank now. For flow I have a sedra 9000 return, 1 coralia 1400 evo, 1 tunze 6045, 1 MJ1200 with sureflow mod. Any more and I will create crazy sandstorms. The MJ1200 already is poorly attached because of their crap rubber nipple stickons and im afraid it can fall off anyday putting 1600 gph into the sand.
** update, achilles came out of his rocks an now moved into the corner where the other tangs resided. PBT has at this point relinquished control and when he swims by AT, he is submissive. Now, its desjardinis turn (who is also smaller than AT but bigger than PBT). They dance for a while. At this point, the biggest loser is the small yellow tang with a nice gash on his side. AT has 1 gash also but things are settling down and I hope they will pull through. I figure with 4 tangs, 2 gashes are the cost of doing business (altho i would prefer to have none ofcourse).
