hi everyone i hav a platy thats female and cant tell if its pregnant. ive been told that there should be a gravid spot but i cant find any but just a small black dot. the platy is a green colour.
The black dot your refering to, should be back end of her belly near the anal fin. this is the gravid spot, but you can really just go by this for pregnancy..
See my pinned thread at the top of this section (how to know if your livebearer is ready to drop)... it will help you lots.
