Stary or lawnmower?

[PeterEde]

It wassold as a lawnmower but has always been a darker course since i got it.
It seems to have forgotten its a herbivore and eats brine shrimp.

Hard to tell from the pics. Most "herbivores" in our tanks will eat other foods.
There is a general mislabeling/ misunderstanding of the term. An herbivore is an animal that feeds mainly or only on plants. Its digestive system is adapted to break down and absorb nutrients from plants. It doesn't mean they won't also eat other types of food.

That’s none of the Salarias species. That looks to me like an Atrosalarias species, do you have a full photo of its fins out?

The "horns" on that guy are quite unique. My first thought was a Parablennius sp., but I'm currently leaning toward it possibly being Istiblennius meleagris - the Peacock Rockskipper or (apparently) Blue Spot Blenny. It comes a variety of colors (the below specimen being quite dark).

I agree with this ID, it looks almost identical to the photo the OP has shown.

Best shot I have ATM
I'd expect it to be a blue spot Blenny since I'm in Australia and much of our fish come from the GBR.
