Not great had to separate the next day. I've got them in seperation tanks now. That was 2 weeks ago and the smaller one is growing pretty fast without the other.
the small one will grow fast as long as you leave it. If your main tank can handle it, I'd leave it in there. Give it 3 weeks or so. You should see it start to gain size pretty quickly. If you have a separate tank for them, divide it and put both fish in. Leave them like that for a while. I left my female and male for a month, wasn't good enough. I just need to be patient. You'll see them start to clear around if you indeed have a male and female. If they do start clearing, leave divider up for a bit. I like to build their bonds in a big community tank. Seems to work better.
keep us updated.
