I have a pair of Bangaii Cardinals which I bought last year in late October. I noticed their "mating dance" and sometime after that the male carrying the eggs. I asked my LFS about separating them and providing for them to breed without the other tank mates bothering but they told me that chances weren't good and to leave them in my display tank with all the others, nature to run its course... Guess what?! One day I noticed the male no longer carrying the babies and did not see the fry. In my 72g, I have a couple of green chromis, true percula clown, fox face, yellow tang, gold head sleeper goby, flame angel and lots of rock with places to hide. My guess is that they became someone's meal.
