What type of blenny is ths?

Just picked these two guys up from my LFS. They said what type of blennies, but I forget exactly what kind.

I checked my receipt but they rung me up for gobies. Right price, wrong fish.

When they had more color in the store they were brown spotted with blue stripes on their faces and pink on their fins.

Thanks!

 

I think they are gobies, it looks like they have 2 dorsal fins.

 

Gobies. You can tell by the modified pelvic fin and as said above, the two dorsal fins.

They used to come in as "Bullet Gobies" but there are several species lumped into that one. Do a search for 'sand sifting goby" and you'll find it

 

Diamond Gobies

 

Found it: Spinecheek Goby

Oplopomus oplopomus (Valenciennes, 1837) - Encyclopedia of Life

Thanks for the direction.

I thought I was getting a blenny, but guess not!

Any benefit to having a blenny vs goby?

 

Interesting. Never seen these before

 

I forget which species of Valenciennes, but at least one actually eats cynaobacteria (along with the normal sand sifting they do).
