Fish attention

[EndAllTyres-Hoon]

I’ve got a lawnmower Blenny that demands I let him sit in my hand every time my hand is in the tank, this guy was so bashful when I got him he hid for the first three months but now it’s exact opposite if I’m looking at my tank he has got to be right in front of where ever I’m looking, if I’m working in something in the tank he constantly pecks my hand till I hold it out for him to chill on, anyone else have any fish that act like this?
