I thought this would be a pretty fun thread since we're a little ways into 2021, what fish species are still rare in 2021? Just fish that are only seen sparsely / almost never seen in the hobby.
As for me, I've never seen any Trssogobius sp, in person, at a store or public aquarium, Trimma Caudomaculatum, Peppermint Angel of course, Tiger Angels, A lot of the non-captive bred Hawaiian fish I'm pretty sure will not be seen very often now (like the golden dwarf morays and hawaiian yellow anthias). There's a lot of other's I could list, but I'd like to hear other inputs!
