A friend sent me a small starter colony of dubias! They're really fun to watch, I think I'll let them breed for a while before I start feeding them off... had fun making them a bin with some very psychedelic duct tape to hold the two layers of mesh in place on the lid. They are very shy and did not want to be picked up so I had to kind of shake/shoo them all into their new home but now they seem very happy in there, exploring around, digging, and they seemed to enjoy their welcome gift of grapes.
