IMO the only 2 dwarf angelfish worth looking at is the flame angel, and the bi-color angel,
bi-color is cheaper, but still the flame is beautiful
they wont jump,
and as another fish, butterfly fish would be great, maybe like a racoon or heinochus or something like that,
foxface IMO would be ok in your tank, granted it'll be the dominant fish and you must allow it to be, so no other fish that could reach the same/similar size as it, and make sure it has room to hide, once you get them, they'll hide day and night, but after a lil while it'll come out and will be a beautiful fish.
so IMO rather bi-color or flame with a butterfly fish or foxface.
but alot of ppl have different opinions on the foxface, but its is altogether up to you, it wont die off because its in a 55g
but you wouldnt want to put it in anything much smaller
