Nice!
I prefer to use sawdust to make the tank look prettier to the eye, but still. The day before I go get more crickets, they'll often hide in the sawdust, and it's annoying trying to find them.
I used to feed my crickets apple slices, bread, and various other things, but now I stick with cricket quencher, cricket diet, and lettuce just because they don't go off as easily as the other options.
