I'm having an issue with a black tang and yellow scopas. They were together originally, but I had to go FALLOW for 80 days. They were both put in separate QT tanks. I added the black tang two weeks ago and when I added the scopas, he just about killed it. I really didn't think he was going to make it, but he did and seems OK for the most part. Before I give him to someone, I'd like to try an acclimation box. The ones I'm finding seem expensive for just an acrylic box, so I figured I'd ask if I could make one, maybe from one of those critter cages?

After it cools no problems.
