looking for owner of

What would be an extremely large fish tank, and i was told has a sheepshead wrasse.

Now i dont know if this is true or if theyre on this page, but i was talking to a coworker and she was telling me about how a friend of her family has a very large fish tank (which she described as taking up half their basement) and has a large blue fish in it and after making her search saltwater fish online she was fairly certain that the fish was a sheepshead wrasse

 

Thats what im thinking. Hoping she mis identified, but thats a fish, i find hard to misidentify. She said the person had gone to school for marine biology, so im hoping that if it is true, theyll have some amazing setup to see
