Best Pygmy angel?

[Wen]

IME, Cherub (Atlantic Pygmy) or the White tail (Pacific Pygmy) angel are the smallest of the dwarf angels. Actually the Fisher angel get large 4+ inches (per Live Aquaria). Certainly LA is NOT the authority of these but if I am you I would do more research on size of these before buying them.
IMO, 33 gal is too small for any dwarf angel long term. Good luck

@OrionN
I am thinking about adding 2-3 Cherub angels to my tank and asking your opinion...?

280 gal mixed reef, feed 5x day (ROE, nori, whole clams or LRS and 2x AFS pellets)

Peaceful group of fish:
emperor, bellus, flame hawk pair, clown pair, corris & melanarus, 5 pearly jawfish, white tail bristletooth, hippo, atlantic blue, CBB, gramma

These guys would be the fish last addition.
Thank you.
