I'm kind of considering breeding angels. I'm getting a 30g, which is a 3ft tank and maybe 16in tall. I think I would put maybe 6-8 in there, either the natural looking ones or the white ones, and wait for them to pair. After that, I would move a pair into a 10g breeding tank and have them spawnin there, remove the angels, and raise the fry artificially. I've just heard too much about having a 'bad' pair that kills all their fry/eggs.
