Just thought I'd share my experience with this fish. I bought a male American Flag Fish appx 5 days ago. While this fish is beautiful to look at, it did not eat any algae or touch any plants, which is what it was supposed to do. For 5 days this fish looked unhappy and kept looking at it's reflection on the glass. I only got one male because my LFD guy did not recommend more than one because they might get aggressive towards each other. Well today I brought 2 females and the male has never been happier. In fact all 3 fish were actively eating algae and nipping on the plants, which the one male has never done before. I'm guessing these fish need to school or at least have 2 or 3 in a tank to be happy. Anyone has any experience with these fish?
