agreed...i have a large P. vitatta that really likes mealworms...so be it....i just feed a couple at a time and a little more often.I've not had trouble with small prey. I know a lot of people say to give X size prey item to X size T. As long as it isn't tiny I've had larger Ts eat some pretty small prey.
Like was mentioned earlier, if it's smaller you may have to feed more often than if you used a larger prey item.
