Dieing Guppies... Female paralyzied

Hello, This is my first time on this sight, and I pray it works! I am a Delta Guppy breeder and I am wondering if anyone would know why my females (2 have died) are being paralyzied. Their upper spine, behind the head, curves in and they can't move, the muscles work, I could feel them, but the spine just was locked... odd huh? Both of them were pregnant and the one was only days from having birth! Pleasse let me know what you think, and I did water testing, PH levels and the whole shibang, I don't understand it!
Thanks, Sierra

 

HI and welcome to the forum. Haven't heard of that. Sorry.

What were the lvls of the tank? Ammonia, NitrIte, NitrAte, PH?

One of my guppies used to do that but it always came out of it and swam normally again after about 5 minutes. I don't know how to help sorry. :-\

Strange. Did they have any other symptoms of disease, odd behaviors, coloration, etc?

 

that happened to my female guppys. their back was bent over and tail went tiny and I saw that the muscle was working it was their back. anyway my guppys died a few days later

 

I'm not sure of the cause but do either of these links help?

The first link is really great, btw. It's the best fish diagnosis site I'd seen so far. Thanks for the tip, Betta!
