Optimally hides should be opaque. The only issue with this one is that you used tape, which is dangerous in a snake enclosure. The humidity & warmth provided tends to loosen tape- which then can stick on the snake when is slides past, with very bad effects. If they get near the heat, for example, the tape can essentially end up being "hot-glued" to the snake. Please re-think your hides- sorry to say- I know you mean well, but it has happened enough times that we know about, so we advise against using ANY tape in ANY snake enclosure.
