Remember those cute little fish that are born pregnant and so easy to raise? At least that's how I remember them from years ago when I last had a tank. Evidently they are not as hardy as I recall.
Thomas and I have a well established, well filtered, well aereated 35 gallon (30 gal actual water vol.) community tank. Ammonia is 0 ppm and pH is 6.8. We have 10 tetras, a rasbora, 2 minnows, and 3 tiny dwarf bottom feeders, some sort of catfish, I think.
Over the weekend, a week ago, we added 6 guppies. 4 (2 male, 2 female) on Friday, from a specialty aquarium shop, and 2 (a pair) on Sunday from PetSmart. By Monday, one of the Friday fish (male) was dead. By Friday, I was down to 3 surviving fish -- the male from PetSmart, and a pair from the shop. This morning, the female is dead, and her male is on the bottom, and will be dead before noon. There are absolutely no signs of fungus, or any marks at all. No warning, except they spend their last few hours with their tails seemingly locked, and trying to swim along the bottom.
I'm at quite a loss.
