Korans are one of the most under rated angels for the aquarium IMO. Beautiful (especially the juvies and full adults), bold personalities, and pretty mellow as an adult for an angel, they are one of the most bulletproof angels available. The intermediate form is a bit of an ugly duckling and can stay in this stage for a long time, but this is one of those fish that can outlive the family dog. I last saw a full adult a few years back and it was only about 6-7" (rare for an adult to be this small) and just beautiful, full of greens, blues and yellows and long streamers on the tips of the dorsal and anal fin, a truly spectacular fish under actinics and 250 watt MH.
lux_06- That is seriously one of the nicest looking juvie Korans I have seen in a while.
