My tank is: 1 male opaline, 1 female gold, i female platinum, 2 pearl, 2 paradise, 6 dwarf neon rainbows, 3 julii corys. All are fairly small and will be moved into a 75 gallon soon. I hear that moonlights are pretty peaceful, like pearls. Having a school is nice to add distractions/reduce aggressions. Try and get smaller 3 spot varieties then timid ones. Makes a beautiful tank!!!!!! I love mine!!!! I have been looking everywhere for banded gouramis (colisa fasciata) can't find them, and I'd like to add snakeskins when I get a bigger tank.
