Got this in tidal creek, south shore LI

 

I read that the inland silvers are usually in lower salinity waters than the Atlantic Silversides.  They max out around 3-4 inches, and none of the Silversides I saw were bigger than 3 inches or so, so I'm thinking I may have found a school of the Inlands.  Can anyone tell if this is an Inland Silver?

Probably an atlantic silverside. Look at the eyes size, pectoral fins location and mouth size/shape. Is it doing well in your tank. They are sensitive fish.

EDIT: Here is a good comparison.

Thanks CU455, they are indeed very sensitive, this little guy died in the bucket after pics. It will be salvaged as bait, however.  

 

I have a pic of another Silverside I caught below.  Based on the below it seems possible it's an Inland Silver, but maybe I am misunderstanding what the gut peritoneum is.  

 

 

Pasting the below from page 10 of this link: http://www.otterpoin...cation Tips.pdf

 

The key distinguishing factor is the gut peritoneum

 

The inland silverside – the gut peritoneum extends beyond the origin of the anal fin

 

The Atlantic silverside – the gut peritoneum ends abruptly at the origin of the anal fin

I think they are all inlands. In your top 2 photos, the anal fin length and number of rays is consistent with inland but definitely not atlantic. And I think you are correct about the gut peritoneum extending beyond the anal fin origin in your last photo.

[Cu455]

I just counted the rays. I was only able to count 13. I was wrong. It is not an Atlantic silverside.

Pretty ironic you posted this. My double humped silverside died today.

RIP Double Hump

 

Thanks for the ID guys.  Solid quick mission this turned out to be, been tough to catch new sea animals around here lately
