Feeling sorry for them, I bought two females and a male from Wal-Mart. Unfortunately, they are all not eating, despite the fact that I have them in treated distilled water with a small pinch of aquarium salt, I've checked the quality, and I've treated them with Quick Cure. My other two males, both gotten from a local-owned pet store, are doing absolutely fine and will eat. I'm very concerned that the trauma they suffered at Wal-Mart will keep them from eating and they'll end up dying. Is there a way to encourage a betta to eat? I've tried Tetramin Tropical Crisps, Tetramin Tropical Granules, and even freeze-dried bloodworms! Nothing seems to work for these little gals and guy. Would brine shrimp encourage them to eat more than what I've tried? I appreciate all the help!

Normally betta will start eating in very short period whenever they changed the new environment. Try to check the water temperature. I am believing you are not from tropical country. Low temp will stop them to eat or slow down the digest system.

Unfortunately, I'm not from a tropical country, no. I'm from the state of Virginia in the United States, and right now it is winter here. But I keep them in a pretty warm room, as warm as I can make it (about 70 - 72 degrees F.). Unfortunately, one of my Wal-Mart rescues died today. It looks like she had Dropsy or some blood under her skin, so there was nothing I could do...but it doesn't make it hurt any less. I think I'm just going to have to get heated tanks for them.

distilled water is not good for fish. it doesnt have the minerals etc. that fish require in their water.
