So yesterday, I bought a school of six Gold Danios to add a little more life to the top of my tank. I definitely achieved my desired outcome, cuz they are a non-stop ball of energy, but I noticed something interesting while watching them. Of the seven fish species in my tank (Gold Danio, Neon Tetra, Kribensis, Bosemani Rainbow, Marci Rainbow, Angelfish, Clown Pleco) 6 of them have yellow as part of their color scheme, with only the Neons breaking pattern. I find this interesting, anyone else have an opinion?
