Anyone can browse our forums but you must be a REEF member and logged in to REEF.org to post.   You will be able to post up to 3 images for a single posting.  Our Fish and Invertebrate Identification Forum should be your first stop on the way to answering “what the heck is that critter I saw?”  Some things to consider when posting a picture to the forum are:  clarity and focus, be sure you can see the mystery critter clearly and distinguish identifying marks, full body shots are best when possible; if not clear in the picture itself, please indicate size of the fish and any behavioral notes that may help in identification; location of the sighting and other dive related information such as depth, time of year, and habitat description (check out http://www.fishbase.org for guidance on habitat use for species or a regional reference guide book). 

Please note that the geographic focus of postings to this forum should be limited to the REEF Volunteer Survey Project regions (coastal areas of North and Central America, the Caribbean, and Hawaii) and the primary taxonomic focus should be on fish and Pacific coast invertebrates.  We will not have official forum moderators.  Our cadre of experienced surveying members and other fish experts will help with identification.

Good morning, I found this little guy in about 20', Cruz Bay, St. John. It was only about 3" long.

I only have my "In-A-Pocket" with me.  Any ideas?

Thanks..

I think this is a juvenile grunt, but am not sure. Perhaps a cottonwick?

The little guy is about 1 inch long.

Hi, fellow fish geeks!

I attached screen shots from an underwater webcam at Curacao (http://tinyurl.com/7q5hmdw). I snapped the first image around mid-day and the second image in the morning.

I think these guys slightly resemble rainbow runners or boga as shown in the Humann/Deloach Reef Fish ID F/C/B book. Fixing to load up the DVD to check out the alternate images; wanted to post here in the meantime. Whatcha think?

(Edited 4/25 to add another photo. Second photo shows yellow noses, which have me leaning toward boga.)

Hello!  These pictures are extracted from a movie so I hope there is enough to see to ID.  I thought I was filming some kind of ray but I don't see a tail when I viewed the movie.  About 50 feet, water temp 81F, Punta Tunich Cozumel.

Thanks!

Hello,

Of the top 6 pictures, I'm seeing Bucktooth Parrotfish-except there is no black margins on tail and anal fins. Then I think perhaps there are 2 different species, unless they are different phases of the Bucktooth, or something completely different. Fish Base's Bucktooth looks totally different. 

The bottom 4 pictures, I'm really confused about. THe 3 pictures that show the white spots along the dorsal fin and white tail blotch, match a picture on Fishbase.org that says they are emerald Parrotfish, but the Reef Set's Emerald parrotfish looks nothing like that.  Fishbase also has NO listing of a Yellowtail parrotfish. If you search for Yellowtail parrotfish, it directs you to the Redtail Parrotfish page.  So what ARE these?

Thanks---

I recently took this photo in Hawaii. I searched but have had no luck ID'ing this fish. Please help

Stumped again,  Scad, Mackerel, Jack?  Pics-1,2,3- Traveling in a school of about 15. Cruising along the shoreline of one of the south shore bays in 2- 10 feet of water. I know they are not Horse-eye jacks. I know they are not Spanish or Cero Mackerel. They seem to long to be scad. If I had to describe it to someone I'd call it a yellow tail, silver TROUT!!!

Pic #4 Do you think this is another Mimic Blenny> It doesn't look right as a Hairy Blenny. The mouth is too turned up-pudgy. 

Pics # 5-6  Have not been able to come up with anything that looks like these.  Similar circumstances/location as with the fish in the first group but I only saw 4-5 in the group. 

I'm probably missing something again....

Thank You for your help again..

Hello,

Anyone recognise this blenny? Taken in less than one foot of water along the rocky shoreline - St. John. Was flitting in and out and around the blister leaf and sargasum weed. On this day there was some surge. There are several barred blennies, but the two tall first dorsal fins don't give me a clue.

Hi,

Snorkeling north shore St. John and snapped these pics. Looks almost like a diamond blenny, but the head isn't yellow and this fish has another dark spot with neon blue center on rear dorsal fin, which makes me wonder if maybe it's a juvenile. So many fish have these spots when juveniles, then loose them later. The red/orange anal fin is curious also. Taken in about 2 feet of water over a Manatee seagrass bed with sandy, rubble strewn bottom.

Thanks,

Just a snorkeler,
