Queen angel, which belongs to the Holacanthus genus, is the least reef-safe angel. I wouldn't even try.

Also, it seems like you are building a 180g, which is still far too small for a queen angel. It gets absolutely massive and needs at least a 96 x 30" footprint to feel comfortable. By the time it matures, including the caudal filments the total length could be pushing close to 20"!

A better bet would be a majestic angel. It's much more reef-safe than queen, stays relatively small (around 8-10"), and is suitable for a 180g.
