How do I know when my black skirt tetra is pregnant?

[Lanis]

I have a 29 gallon tank with 6 black skirt tetra's and 1 placostamus (sp?) plus many snails and some other fish I can't remember what they are oooops. I was wondering how I know if any of my fish are pregnant as one of my black skirt tetra's is way more fat than the others. How long is their gestation and what do I need to do. HELP!!!!

Yep. They aren't livebearers. Also, they are fairly difficult to breed unless in larger groups of 20 or more, the chances are slim.
