I don’t recommend the blue green chromis in anything but an absolutely gigantic tank, maybe 200 gallons with a school of 15 or more. Even then it might not work out. Anything less and they will kill each other off till there is only inevitable one left. They will be fine at first but the weakest will be picked off over a matter of weeks or months, then the next weakest and so on til there is one left.. Everyone I have ever talked to - says the same thing. It might take 1,2 or 3 years but eventually a school of 8 or 9 will be reduced to one.
I want to mention that the Bangai Cardinalfish are easy to keep but their harvesting from the wild is extremely invasive and not sustainable. Be very weary about where you source these fish, there are some breeders that have successfully bred them in captivity although it is very hard to do. Just a heads up for those because it not commonly known!

Its always better to get captive bred instead of wild caught. For sustainability and captive bred are easier to keep and more hardy than wild caught
