They are skiddish and will need time to adjust, they should warm up eventually but any quick movements or even walking near the tank will cause them to scatter. I know mine still scatter but will come back out if I just stand there for a minute.
As for getting them to grow faster I just feed a few times a day. Keep in mind they just are not going to grow fast like how other fish will, they are just generally slow growers.
