So my male panther wouldn’t take them as a baby either. I tried from 3-5 months old, he didn’t eat a single one. So then I stopped offering them for 3 months, and tried again at about 8 months old. I intended to do the Tough Love thing, where you only offer the roaches and nothing else until they start eating them regularly. So first day, I gave him some dubia and told him sternly “This is all you get! Eat them!” And much to my surprise he went right for them, ate them all, has been eating them no problem for past month, along with all his other feeders (I feed silks, crickets, bsfl and flies, blue bottle flies, supers, horns, and now dubia as well. Trying to breed snails, no luck yet.) I’m pretty happy he just took them and I didn’t have to do tough love since I’m a softy. So maybe stop offering them altogether until he’s 7-8 months old, maybe you’ll get lucky too!
