It is easy to miss the brazilians strike htey are usually really wuick haha. Nice snake.
Even with feeding on subsrate it would have to get a lot of it or some big chunk to get impacted. That look slike the ground up coco husk that is really fine. Yeah you can get more on the rodent because it is "sticky" in comparison to the chunk coconut husk pieces, but it's size barely poses a threat. In my opinion.
