I'll second that- orange cubes are bad, i had a very high cricket mortality rate using these and they're also super expensive, get simple polymer water crystals, they are used in gardening for soil, i got a packet off ebay for 8$, that I'm using for more then a year now and as a food- just anything you have laying round, fruits, veggies, cereals, bread, dog/cat food,
by the way none of my crickets were eating repashy bug burger, so I'm stuck again with a bag of repashy something.
