Ray gender mix for 600 gal

  • We are currently upgrading MFK. thanks! -neo
We have the same size tank and have 8 rays in it, and 5 out if the 8 are between 12" and 16". And the others are between 8" and 12". And they have a ton of room. Not at all crowded. So 6 should be fine, and if I had to chose a ratio I would do 4 females and 2 males.
