White Tube?

[TheSims3Dude]

This tube like thing is near her anal fin, it's darker, like a black color on the inside, it keeps "contracting" it looks like, it gets bigger than smaller, does that mean she's going to give birth? All the other fish are near her, I don't know what to do.... Help?


P.S. She is pregnant, so is that the birthing tube contracting? It's been "contracting" for about the last 10 minutes, and she's kinda breathing heavy..
