Hard to keep coral you find easy to keep

[Gumbies R Us]

So last week, we had a thread about "easy to keep coral that is challenging to keep healthy/alive," but what about the other side of the coin: "hard to keep coral that you find easy to keep healthy and alive?" I want to know what corals in your tank are regarded as "hard to keep" but do exceptionally well in your tank. Photo Credit: @sunnysidecorals

I think I’ve lost all types of coral I’ve tried to keep with one exception… acropora

Obviously must be easy.

SPS coral. I have an acro collection too.

Goniopora...grow like crazy and never seem to have any issues.
