It's a really long story! Did the new aquarist thing and added fish too soon or added fish that I couldn't keep healthy... In a fit, I decided to dumb it down. I added three damsels, a domino, gold tail and a three stripe. At first all was well with the tiny little watchman, the royal gramma and my mandarin. Now though, the domino is just plain mean. Watchman, gone, gold tail, gone....Does anyone have any tips other than just plain goin after him and cleaning up later?!
