Hi all,
We all sometimes keep snakes in tubs especially neonates and I would recommend that all keepers have clear or at least opaque lids. The reason being , after I had cleaned out one of my b.nasicornis I hooked the snake and returned her to her freshly cleaned home. I clipped the lid down and replaced the tub back into the vivarium. It was lucky for the snake that I took a second look before walking away as she was sitting with her nose pressed up against the lid with her tongue firmly trapped underneath . I unclipped the lid quickly and fortunately she recovered 100% , although she did not tongue flick for a few days.
Just thought i'd warn other keepers to watch out for this.
