Hey all! Im new to this forum but not to the fish hobby. I have 2 female guppies that are very pregnant and ready to drop soon. I moved them over from my all female tank to a 5 gallon birthing tank. Ive had them in there for about 4 days now and they still havent dropped their fry. When they were in the all female tank, their gravid spots were dark in color but now that they are in the 5 gallon tank, their gravid spots have turned pinkish. They havent dropped any fry, I know this because they are still the same size if not bigger. When I put them in the birthing tank they were squared off and they still are. Does anyone know what could be going on? Any advice would be great, thanks.
