Anyone have a harlequin tusk in a an acrylic tank? I have a red sea sailfin, regal tang, naso tang, and an emporer angel in a 125 acrylic fowlr. I would like to add one more fish and came across a really nice looking harlequin tusk that I'd like to add for my last fish. Tank is running great and all of the fish get along very well. Would an HT be ok? Also has anyone kept one in an acrylic tank? I've heard that they can scratch up acrylic with their tusks pretty badly but 2 reputable lfs have told me not to worry. Thanks!
