I have a 29 gal with 1 yellowtail damsel 2 clownfish a 1 yellow watchman goby I would like to have corals. Are there any pygmy angels that could work in suck a small tank with corals?
Not that I'm aware of. Those take 50+ gallons when mature. That size tank with existing stock that's already semi- aggressive and you'll likely end up with all kinds of problems. And then you add in corals and I doubt you'll be very happy with an angel (pygmy or otherwise).
A flameback of cherub may work, I had a flameback in a 29 with a longnose hawk, pair of clowns, and multiple corals without issue. Just make sure you have plenty of rockwork for established territory. Also, each fish is different so take my experience with a grain of salt.
