Reef Croaker and Ringed Blenny -Maybe


Hi Louis,

Here's one more little fish. Surge area, sitting under a rock overhang in about 2-3 feet of water.  Could it be a Ringed Blenny? I know the picture is bad. I didn't know I had him in the shot until I got home.

And here are a few more "Croaker?" Pictures. Looking closer at these, the brassy horizontal dashy lines on the fish's side, do make it look like the picture of the Reef Croaker.

Hmm... It would be very unusual to find a Starksia sp. in such shallow water. I don't think the bars usually continue onto the head of most Starksia blennies either. My best guess now is a Lythrypnus goby.

Yes, those are definitely Reef Croaker. Looks like you've found a great place for them!


Does it have a common name?

Does Lythrypnus goby have a common name?

Lythrypnus Goby Genus

No, Lythrypnus is a goby genus - it's a whole group of gobies. Honestly, even if you had a perfectly clear photo I don't think we could positively I.D. because I don't think your fish has been photographed before.

Do you see these fish often?


Rusty Goby

Hard to tell for sure from your photo, but I think it is a Rusty Goby.  They can be in water as shallow as 2 feet, like hanging out in crevices, and can be found in the Floirda Keys.

Rusty Goby

  I've seen the Rusty Goby a couple times and have a picture. I can't figure out how to load a picture in this reply.  I always see them on the ceilings. His head looks a lot wider and taller (heavier) than the mystery fish's.  But it may just be the angels of the pictures. The stipes match. Yes, too bad the picture's not better.  Just a snorkeler, islandbarb

I think it is a rusty goby

I think it is a rusty goby (Priolepis) -perched like a goby.. and large, stocky, and big-headed (and out in the open)--less likely but possible for a Lythrypnus goby if it was less than an inch long, not a Starksia blenny, which additionally have a pointy face, sit in an S position, and don't like to be out in the open, especially in shallow water (only one species in shallow in most places).


Yes the others are reef croakers- very common in the continental Southern Caribbean.. maybe they like murkier waters.



That could be about the Croakers. The only place I've seen them is in one of the murkier bays.

Thanks for all you guy's help.
