I recently rehoused my H lividium into a bigger tank. Before it had dug itself a nice little burrow and i was never able to see it. Since i have moved it, it has not even attempted to burrow, but has pretty much put a thin layer of webbing on the substrate and on some of the walls. Did i do something wrong? It seems to be pretty healthy, and aggressive, and has eaten just fine. For some reason, it has lost it's desire to burrow! Help! :?
