Let me start from the beginning. When we set up the new tank, we had the fish we've had for a few years. They are a mated pair of Percula Clowns, a 4" Fairy Wrasse (not sure which, exactly) and a yellow Tang. They get along fine. I really wanted to add a couple of fish, and Wrasses are one of my favorite fish, but I was a bit worried about adding any more for fear of trouble with the existing Wrasse. I started reading, and found some good info on having more than one Wrasse in a tank, basically the Fairy/Flasher Wrasses seem to be the ones to go with and they are hardier than most and generally safer on Invertebrates.
So, I got the two, figuring maybe two would keep the Wrasse from beating up on one too much. When they were added to the tank, both seemed quite at ease with the other fish, and were coming out rather quickly to check out the surroundings. The Wrasse seemed curious, but ok.
Then....the Yellow Tang went ballistic. It went after the first Wrasse like it was going to tear him up. Absolutely relentless. Fortunately the Wrasses are fast and small and he hid in the rocks. As soon as the Tang noticed the other one, he went nuts again. I was worried for this one, the more peaceful McCoskers. These fish don't stress well, and we decided the Tang would have to take a swim and rest in the 75.
Yeah, right.....catch a Tang in a 120 with way to many Acroporas.

So Becky, the patient fisherman and fish extractor got her nets and waited as any bass fisherman does.......watched, herded the Tang with nets......and waited. After about an hour or so, a tired Tang....and Becky calling it things that would give anyone a real self esteem issue, I tried, very unskillfuly to help. Got close a few times...but no. So I mentioned the fish trap, have had it forever and never used it. She was getting a bit tired and grumpy by this time, so I got the big ol' trap and set it in the only place it would fit in the tank. As we were discussing how it would NEVER work, I put a bit of food in it , and that Damn Tang swam right in like it was nothing....closed the door and still laughing, put the Tang in the 75. Been in there for a couple of days now.
Now, what to do. Leave the Tang in there for a couple more days and then put it back in the 120? I plan on having a Tang in this tank, I'm not really fond of them, but they are helpful. I hope that the "time out" will allow the other Wrasses to get comfortable in their surroundings, and maybe the Tang won't be so ornery when we put him back in. Opinions, anyone?
