Fish stock is small mainly just the same fish from the 120. Only new is clown tang. Also have pair of clowns, Sixline, Midas blenny, royal grammar, Splendid dottyback, goldhead goby. I had a hoevens wrasse but he seemed to be shy when I put him in new display, burried himself and I saw him once a week maybe. Lately haven't seen him at all so I think he is gone but when I first got him he literally went unseen for 2-3 months and then one day he was out. Hoping he still is there cause he is not only my fav fish but my longest lasting fish of 4 years
