New Platys Mum

Are my platies definately pregnant or just been overfed by the previous owner?? I have had them almost two wks and they look huge there is a white tube thing sticking out but poo is coming out of that?? Sorry I sound dumb but must ask!!

i actually just got slapped i looked at the pic and swore loud enough for my dad to wake up opps haha.
that is either one cruel overfeeding ex owner or heavily pregnant females

Holy poop! They are HUGE! I have NEVER seen one get that big with babies! Congrats!
