Hey guys! So I have a lil question I didn't know if anyone here could answer. My platy is ready to drop her 3rd batch (I'm hoping tom or the next day?) but has anyone noticed what looks like a bubble inside the mother located in her body but right under her top fin? I've heard of the Gravid spot. But this looks like a clear bubble. Just didn't know if this had to do with pregnancy and what it might be...? I think I notice it's gone or barely noticeable other times. Thanks
