And even if it worked before (somewhat) and it works now, eventually there will come a time when it doesn't.
What about if you need (should anyway) feed them in their home, feeding 2 snakes in the same enclosure is a recipe for disaster. They may take it from the tongs for now. But sometimes you have to leave food and walk away. Sometimes one finishes first and is in feeding mode while the other still eats. Yup, you may find 2 dead snakes once, one half eaten by the other.
What if you need to monitor one because of a fast. Need to monitor their waste. How would you know which poop goes with which snake ??
Just altogether a bad idea and possible husbandry nightmare in the making...
