Holly9937 if you found out you are pregnant...congratulations. I cannot tell you about the dangers of fishkeeping in regards to pregnancy, but I can tell you if you have a cat, be carefull. there are dangers with changing the litterbox and toxoplasmosis(sp?). Also if you have a female dog they have worms. Even though people worm their female dogs from what the vet tells me... the opportunity is always there to pass them on to humans. Something to do with their heat cycle.
