We have a fairly new tank with 2 female swordtails and 1 male with various other (non livebearing) fish. We brought home 2 pregnant guppies which we kept in a breeding net. We were told they were ready to give birth any day. The next day we found 2 fry in the main tank swimming around. I'm assuming they were not from the guppies since they were kept separate. The babies are orangish color and look like they could be swordtails. Any way I can tell for sure? I didn't think the swordtails were pregnant - they didn't look fat at all.
