Strange guppie!!

[NatalieandOliver]

Hi all!

First post here and I need some advice. In my first tank which is a small 15ltr corner tank I have 4 female blue tailed guppies ( 3 of which appeared pregnant, one seems to have aborted and the others still havnt given birth and show no signs of giving birth after 3 weeks) 1 beautiful male, and we recently got a blonde female from pets at home.... She just sits at the bottom of the tank flapping back and forth not moving from the same spot and has been like this for 3 days now.... She has no interaction with the other guppies whatsoever. Is something wrong with her or is she just an anti social Mardy bum?!

Sorry.... I waffle! Lol

Welcome to AA!
Just a few questions:
How long has the tank been set up?
Is it cycled?
What are the ammonia, nitrite, nitrate and pH?
When was the last water change and how much?
Unfortunately 15L is too small for so many guppies especially with fry on the way. I would suggest a 40L tank with a separate one for fry or a 80 - 100L tank if you plan to keep them all together.
