I have a pet fish but my fish won't eat anymore.

This could be a number of things. When was the last time you changed its water? Is the water clear or murky? If it has been over a week and the Betta is in an unfiltered fish bowl, then you need to change it ASAP. Does the fish look sick? Spots, not acting like itself, etc. Have you changed anything it is bowl lately that would cause it stress? Have you been over feeding it (if you use the pellets, most Bettas will only east a few per day)? That could be a cause. How long has it gone without eating? Most fish can live up to 5 days without eating. If it has only been a day, I would not be worried.

Contact one Ms. Drucilla. She knows quite a bit about betta fish.

Hi! Bettas love bloodworms. You can find freeze-dried bloodworms at pet stores and even department stores like Walmart. My bettas always went crazy over bloodworms. :-)

I'd go with the water change as well. If it's in a bowl or 1 or 2 gallon size container, you should be changing 1/2 the water every other day. As someone already said, just because the water looks crystal clear, doesn't mean it's not toxic. You can't see ammonia, nitrites, and nitrates in the water, all of which can kill fish very quickly, with the exception of the nitrates, usually that kills at a higher dose.
