It would be a while before I can hope for fry; the animals are still in a bare quarantine 5.5g, and I don't think they will breed there. They, however, look good (rabauti's I've seen before were always wrong...either very small, or unhealthy, or too few)... They will end up in a 30g with rainbows in a month, then we'll see.
I'm toying with the idea of asking the store to get me 2-3 more...he said he can. If you are interested too, drop me a PM (the store is in Queens, should be within reach for you, I paid $5 per fish).
