Guppy Fry Spinning In Circles?

[iheartjeffrey]

I just went to my tank of guppy fry and noticed one fry on the floor on the tank continuously spinning in circles! She'll swim upward but when she does... she does it in a upward spiraling type of swimming. I don't see any visible injuries on her either. She's one of my 4 week old fry. My fry are in a tank thats about 7 Gallons, with a 10 gallon filter, submersible heater, and bubbler. They've been in this tank for maybe almost a week now and there are 87 fry total all about 2 weeks apart in age. None of the other fry are showing any of this fry's symptoms either. I was able to video tape the fry but unfortunately dont have the cord to connect to the computer.Can anyone help me out?

Hi, just thought I'd ask if there's any improvement with you fry? I've never noticed any of my livebearers do this and I don't know what would cause this. Hopefully it's nothing serious.

Cheers,

No Sadly the little gal died about an hour after posting this. She was the only one doing the odd spinning. I didn't notice any type of sickness on the fry but when looking closely I noticed to the left of its head from above view, sort of internal bleeding. I was guessing where the fish's brain would be. No clue how that could have happened though.
