What do you mean substrate? I didn't know they needed substrate o.o I thought they only needed a cup of moist sand to lay eggs in? If not please tell me what you use ^^ I'm not very adept at telling regular grasshoppers apart from lubbers, because I have not seen them side by side. I think I have regular grasshoppers and not lubbers, cause I thought lubbers were more colorful.
They seem to be eating the wheat germ I put in there but show no interest in the greens and so I don't know if they are getting any moisture. >.< Also how strong of a light should I have on them? I have a 15 watt on them now, and they are in a ten gallon tank.
Sorry for all the questions, I just want to make sure I get it right before I try another batch.
