If given the proper time and attention to the training process, I think there's about a 70% chance you would succeed in getting it to eat frozen mysis. You should try to target feed it so the fish don't steal its food. Often, that sort of thing keeps it from proper training. If you will quarantine it, then you might find training it to be easier.
Yes. Brine shrimp is a bit low on the 'normal' food chain for our ornamental fishes. Enriched serves it purpose, but in a nutritious regime, I would limit even enriched b.s. to less than 3 feedings out of every 21. Decapsulated b.s. eggs mixed into a gel home made formula I think is a good addition.
You're welcome! Good luck!
