CSI: Fish tank

About a week ago I decided that my second fish tank was prepared for the acceptance of new fishes. So mom and I ran out to the store (PetCo and not our usual PetSmart because I suspected that the Co would have Female Guppies,) and I purchased four female guppies and two neon tetras.

A week later and only one of those four is still swimming, and even she doesn't look so good....*tear*

It should be noted that I put my three male guppies in with the girls one day after their introduction to their new home....and have since removed them upon discovering that the tails of the deceased fish are bitten, and these boys have a track record of biting each other.....However, it has been suggested that they may have nibbled post-mortem.......

The tetras are looking peachy (they were in the other tank). As are the male guppies, which were successfully transferred to the other tank. I am beginning to believe that perhaps it had nothing to do with the biting, but with the females themselves or with my tank......but then I'd think that the boys would be ill.

I need a guppy coroner.
Time will tell. It depends on whether my last girl survives....

There seems to be many sad things happening lately.....Such as the fish incident, and how CSI ended last Thursday....Other things too, but I can't think of them right now.

MY POINT IN WRITING BEING: please pray for my fish, her name is Judi and I would be ecstatic if she survived, she'd be my second miracle fish.
Technically, I could still take the dead ones back to the store and demand reimbursement...but fishies are not to be bartered with (that is unless you bought a ten dollar fish,) I think it is insensitive....AND so I have humanely flushed two of three...

k, sorry that was prolly boring, but writing it out helps my thought process....though apparently thinking it through does not solve much in this case....
Anyhow, I am listening to some lovely music.
