Yeah, I am thinking of selling my 3 Silvers cause they are quite piggy! They outcompete Triggers! Yes, they are in saltwater and the biggest is coming on 5 inches. I want to get more delicate stuff, and fish that aren't quite so energetic to get food. I currently have them in a 209G tank with a 4 inch Niger Trigger, 3 inch True Bursa Trigger, 1 inch Huma Rectangle, 5 inch Lunare Wrasse, and the newest addition a 3 inch Flame Angel. Scats can survive anything though, and are extremely hardy. Great for the beginning brackish aquariust. My guys live in harmony until after I feed them and they are fat, the biggest one chases the other two. Don't know why but oh well!
