I did a bad a thing and got a discus from Craigslist that is not eating. The person I got it from mentioned that it is not eating. I need some help to try to make it eat food. I heard garlic can help stimulate a fish to eat but have never tried it. Any help and ideas would be great. I don't know anything about its past except that it stop eating. Let's not make a four inche discus die.
