Found some info for you on the net.
As for the Scribbled Angel, they are about Moderate hard to keep.
Not too bad, I would say about the same as the rest of the angels.
Majestic Angel- This one is harder to keep, and will bully other fish, so it has to be the #1 guy in there.
Asfur Angel- This one will live in an anquarium but it has less of a success rate and is more fragile.
Maculosus Angel- Easy to care for, hardy fish.
Queen Angel- One of the harder to care for angels.
Keep in mind most if not all Angelfish dont like other Angelfish around, so you only can get one
