Two tomato clowns, blue damsel, yellow tail damsel and a really mean three stripe damsel. I've learned that you can't catch a damsel in a reef tank. So the two tomatos were my first priority because the female would bite me every time I went into the tank. I could not catch those two clowns no matter what I tried...........unfortunatley I figured out I'm not smarter than a fish......let alone a 5th grader. So, I tore down the tank and got the two clowns. The tomatos were so aggressive that I had never added any new fish so I never realized that the three stripe was aggressive..........until later. After removing the tomatos, I decided I'd like to have a yellow tang and a powder blue (tangs are my favorite fish) but unfortunately the three stripe killed them both and a good size naso as well. Not only was he a killer, he would make a mess of the sand in the tank. He would hunker down and swish back and forth pushing sand all over my corals and damaged a chalice he buried. After months of trying every trap and technique I could find on reef central, I finally had enough and for the second time in 6 months, I tore down the tank. This time, I wasn't taking any chances and I took out every damsel including the three stipe, the blue and the yellow tail. Now, hopefully I can have the Tangs I want.
