Compatibility Key

  • Green: Highly Compatible
  • Orange: Moderately Compatible
  • Red: Rarely Compatible

How to use the Chart: Simply identify the species of fish you want to mix. Find the square on the chart where the 2 species meet (NB: if you can't find a match try reversing the mix, i.e. instead of Barb and Guppy, try Guppy and Barb). The square will identify the compatability rating of the 2 species.
