Good point, with my antennata I just relaxed, remembering easyness of my lost volitan. Even mandarin dragonets, which arrived much later, now are weaned to eat frozen food - antennata just looks incomprehensively at the frozen shrimp piece, then on me - I clearly feel how it "shrugs shoulders".
A lot of fishes are troublesome somehow - including agressive
cleaner wrasses and clowns, peaceful but with potential puffers and big-mouthed lions and anglers (?scorpion fish family, bottom dweller with short stump "feet").
There is thread about volitans, but all is applicable to the other lions

Basic requirements are: source of food, not too bright light, quite closed caves to have some peace and quiet, good filtration/skimmer, non-bothering tankmates - even fast-swimming wrasse or ignoring, going over your head mandarin, could irritate. Anyone with pincers and sharp teeth can bite off lion's fins. I'm keeping salinity at 1.025, but had read that some lions prefer up to 027. As a cleanup crew, I have hermits, what may be not a good idea - they killed all but one
astrea snails, and have a turbo-snails. Nor urchin, nor serpent star were useful for cleaning.
Who was eaten, despite fed lion (not well-fed, it's matter of saltwater origin of the small fish, which is more useful for a lion, and of the timing - when lion becomes hungry and you are not around to feed) - green chromises on the picture above, just right size. Also, when herded, they don't run away, but are trying to hide in the corner - easy prey.
