No compatibility issues.I am familiar with the delicate nature/poor shipping of blue reef chromis, but compatibility wise, any issue adding a blue reef chromis trio from divers den to a 90g reef with the following live stock:
Midas Blenny
Helfrichi Firefish
2x Blue Star Leopards
Matted Filefish
Copperband Butterfly
And then afterwards adding
Sunburst anthia
Melanarus or Vroliks
Flame angel
Thanks
