golden is the hardest angel to keep in the genus Centropyge (by experience and by literature). others may disagree.
colini is rarer but also hard, if not, just as hard. but it's less shy than golden and easier to get feeding.
colini is found in greater depths than golden angel and most die from decompression illnesses.
colini is seldom caught by cyanide because of it's depth and it's less shy than golden. golden are almost always cyanide caught because they are extremely cryptic. however this is not to say that colini are not cyanide caught. some are.
they always die anyway, very hard.
i've tried 4 times. each time manage to pair. and all times manage to get feeding. but died from decompression problem. they are also very sensitive. if something happen to the tank they don't like, they can just stop feeding altogether.
if you want to try, get those that come in from Fiji. Fiji colini cost many times more and is very much rarer but they are not cyanide caught and tend to have better success.
your best bet is to wait for season during philippine shipments coz when there's season, they will start trickling in and you can try them.
best of luck. one of then nicest and most beautiful dwarves out there. and they have very unique swimming style.
