Anything the adults can eat can also be eaten by the nymphs. It may even be easier because nymphs take smaller bites than adults so less leverage or biting power is required to scrape off bites.I have been feeding my nymphs cooked hamburger meat and fish flakes, they happily munch on them, but wont eat any fruit,vegetable of any sort, or dog or cat kibble, I guess because there too hard for them to chew yet.So what else can I feed them?
