I purchased a group of about 7 sold as lemon chromis from Live Aquaria and identified as A. ternatensis by them maybe 5 years ago. My thought was they would be an attractive shoaling fish. They did shoal more tightly than blue green chromis but possibly showed more con-specific aggression. Unfortunately all but one died in the first 10 days from what appeared to be uronemia. The survivor is currently 6-7cm and looks like a giant (ugly) long finned blue green chromis. It is pretty aggressive. I don't think they are a particularly common fish in the hobby nor do I expect them to become more popular.
