Just wanted to ask for some opinions on one of my girl guppies. All of them came to me pregnant and have been in the tank nearly a month. She was the biggest of the group, both pregnancy wise and length. Almost all of my other girls have dropped and some are even pregnant again but she seems to be holding onto her fry. She's also much bigger in the belly than any of my others got. Is she gearing up to give birth or should I be worried about her? She's rubbing up against the decor and is much slower moving than the rest but other than that she's behaving normally, no hovering or sitting at the bottom.
