All of the offspring will be albino.
Nobody has yet proven the nature of the genetics behind the coral trait. Based on the information available, it appears that the coral trait is not a simple recessive - beyond that, little has been learned and there are many possibilities.
The simplest summary of what you might expect in your litter would go something like this. At birth, they may all look like regular albinos or some may be distinguishable as likely coral albinos - it often takes as long as a year to 18 months for some coral albinos to start "coraling up." Whether distinguishable at birth or not until later, you would most likely end up with some offspring that are clearly coral albinos, some that clearly do not appear to be coral albinos, and some that lie within a range in between where it is difficult to say with certainty whether a given individual is a low-expression coral albino or a nice looking regular albino. The variability in expression of the coral trait is one of the aspects that has made it difficult to decipher the genetics.
Consider this litter's appearance at birth....
And three from that litter at about 8 months....
And two of the nicest corals from that litter at 17 months (the second one is the pinkest of the three in the photo above)....
Without a better understanding of the genetics behind the coral trait, we don't have any basis for stating an expected ratio of coral to regular albinos, etc. The qualitative description above is about the best that can currently be done.
