thanks for your reply. I told him i would have to ask my green Chromis' if they would be happy sharing the tank, i guess the answer is NO!This is called a Behn’s Damsel, not a real Chromis. Attractive as juveniles but become a lot more dull once mature, plus aggressive even for damsels. I would recommend something in the Chrysiptera family or some Pomacentrus.
Azure, Talbot’s, Rolland’s, Starcki’s, Yellowtails, true and false Springer’s. Starcki, Yellowtail are a but more aggressive than the others though not the worst.
The Neon complex of Pomacentrus have some pretty ones. Some people have also had luck with the Lemons.
