I dont like feeding crickets, they smell and they are too darn expensive in the pet shops.
I bought a lobster roach colony 2 years ago and I have never bought any food since then. (saving money all the way)
I also have a Hisser colony but I'm not too keen on feeding them to my T's since they have a very hard exoskeleton and can break the T's fangs. When I see a Hisser that is freshly molted and is still soft then I give it to the T.
I every now and then take a few of my brothers pinkies and feed it to the big T's (but only once every 4 months). poor pinkies
