Goldfish are da bomb...should be their own food group!! Lol. I especially like the extra cheddar ones...My gymmies don't particularly care for them, but my youngest and I LOVE them!!
As to snacks and eating times, my gymmies are both very slender so if they eat late at night, I don't care...at least they are eating!! They like chicken, beef(done in crock pot) cheese, apples, strawberries, peanut butter, soups and crackers, sandwiches, tacos and burritos (we live in the southwest) sushi...whatever you can get them to eat!!
