@ marinenut,
My "bi-color" blenny acts much the same as your "midas" - *He is always the major attraction & attention getter by visitors (once noticed) --
It is, like you say, almost like he puts on a show everytime you walk in room..
My wife will sit and "chuckle" for long periods, just watching him. *
If I wasn't so guilty of the "always room for 1 more" syndrome...

- I would consider another...but really, have the draw the line at any more fish for a while ...
(except for a pair of little citron clown gobies, ummmmm

) ( i truely do have an "illness" about these critters *

) - *
Rgds,
