Just becareful not to overfeed. They have voracious appetite to a point to cause a problems from over eateting.
Cant believe
LFS used/recommend BS for such carnivorous fish. Even will require tons of Mysids to fill it up. You can use shrimp or prawn/
krill/silversides/killies/spearing/ or other small s/w fish which are cheaper than what's usually sold in lfs.
Can also treat with Live Ghost shrimps (kept in f/w) to keep them alert/in shape (excercise while chasing).
When bought from supermarket, just steam it a bit or soak in f/w for a while to sterilize, that is if desired.
Have fun and becareful. If you are allergic to Bee Sting, not a best choice of fish to keep.
