Answer
Hi Damian
Your question just showed up in our answer pool, so sorry for the delay in answering.

Mollies and tetras, I don't think that's possible for them to cross breed.  I know that platies and swordtails can, and I'm not for sure, but think mollies and platies can, but not with tetras :)  Tetras are egg layers also, where as mollies are livebearers.  They may just be protecting it for some reason.  

Hope that helps!
