Well right now I have some danios, tetras, otos, an angelfish, an african dwarf frog, and i will probably get a couple of cherry shrimp. I was looking into an electric blue jack dempsey or a green terror. I want to get something young and small, but i want it to grow to about the sizes of those fish. I will have plenty of places for those other fish to hide from it if it starts to get hungry, but i want something that will "wow" people when they see it...obviously
