Classic step for introducing new fish to an established fish of the species. Glad it worked.Thanks xraycer, I did it and now they are swimming around the tank with no problems. The dominant earth eater isn't picking on them.
Other tricks are introducing the new fish at night with lights off (especially when there's already a group) or using a clear divider for a while, which often leads to the established fish eventually accepting presence of the newbie(s).
