Quick update: The GSE is so much more capable and healthy than the banded. As soon as it smells any food it is out and hunting and will find the food even if you just drop it in randomly and of course with that ghost shrimp don't stand a chance. Like the BSE it will bite anything in the tank when in feeding mode and like the BSE those bites are completely harmless with both me and the angelfish not being bothered remotely. It also happily puts up with being handled though I try and do this sparingly as I'm not sure whether skin oils are detrimental to their skin.
The BSE on the other hand needs a lot of help with feeding and seems to struggle both finding it and eating food. I'm worried about the BSE therefor and last I knew the other BSE at my LFS was looking much worse with them also struggling to feed it. Mine is still getting enough food I think as I feed it until it retreats to its pipe but it is eating many times less than the GSE. Both BSE's also look much thinner than ones I've seen in photos and videos online. Not that I think there's anything really to be done other than continuing to feed it fatty fish.
