flame angel pair breeding chances

[shabreeson]

I want to know what the chances are of success of a mated pare of flame angels in a 55 gallon if both are introduced at the same time?

what are the chances of cohabitation without being a mated pair?

and of course (everyones favorite) what are the chances of them tearing each other apart?

how much are the chances of success increased when putting three or four in?

tanks too small for 2.

Here is from the Angel breeder guru (Frank) at RCT.

"Tank Size
First off consider the size and height of the spawning tank. A pair or trio of an average sized Centropyge species, like the flame and lemonpeel angel, should be kept in a minimum volume of 50 gallons. Smaller species, like the Fisher’s angel, need little more than 30 gallons. We have found that egg fertility greatly improves when Centropyge are given enough room during the final rise that culminates in spawning. Therefore, the height of the water column in all of our Centropyge broodstock tanks is at least 20 inches. As for infrastructure, we provide a little bland décor in the form of pots or tiles for hiding but also leave adequate room not to restrict courtship behavior. Our best spawning results thus far have been attained in standard, 3-foot high 55-gallon drums and 4x2x2 foot, 120-gallon aquariums. Each of the aquariums contains two pairs separated by a divider."
