I bought 200 silk worms from mullberry farms. I received my order last monday, and they all where dead by Friday. I put them in a bigger container (2 1/2 gallon tank), they were always above 75 degrees, and I feed them fresh mullberry leaves. Any suggestions on how to keep them alive would be wonderful, or if someone could suggest a different worm that is easier to keep. I am looking for worms with no hard exoskeleton. My beardie will not eat crickets, and I will not let him eat superworms or mealworms anymore. Thanks.
