What is the normal coloring for a female betta fish?
There are a lot of potential things that could be wrong, but ich is only one. If she’s got ich, she’ll have small white spots that will make her look like she was sprinkled with salt. The medication for ich is very stressful for fish, and if it contains malachite green or formalin, these are both carcinogens (have been linked to higher rates of cancer) so they shouldn’t be used if you haven’t made a positive diagnosis of a condition it will treat. The same is true for any medication. If she doesn’t have the spots as I’ve described, you should put her in water without any medication. Make sure her temperature is warm enough, 75-80o is good. I’d also find a place for other than with the male, even if she’s in a bag. Being that close will only stress her more if she is sick. If you want to mate them in the future, that’s fine, but you don’t want to put them together until she’s eating, and you know she’s healthy. WalMart bettas aren’t kept in the best of conditions, so proper temperature,
