I just got my first dempseys! i got 3 of them for 15 bucks! there about 2 inches right now, the guy told me to feed them freeze dried brine shrimp.. there all a graysih color right now? is that wha they look like when they are young or will it change when they get used to the tank? also the guy told me its best to feed them more than once a day, he said feed them and then when they eat it all feed them more, until they stop eating, is that true?
