18 = brook silverside (the "new" species, vanhyningi)

19 = bluefin killifish

20, 22-23 - bluespotted sunfish

21 = freshwater goby ???  (zooxanth is the best ID guy for those)

24 = banded pygmy sunfish (same as 1st photo)

Thanks Gerald, I was just looking at the fins and thinking either Brook or Miss Silverside so thanks for clearing that one up.

What's the explanation behind the "new" species?

I was also thinking El zonatum for #1 ...  Gerald has a picture on the forum of an adult that is almost identical, colorwise ... but the high placement of the eyes is confusing. OTOH, when the little ones are in my hand my vision I don't look at them hard enough to see such detail. More likely it's normal for juvvies and I'm ignorant, vs the fish pictured being a mutant freak.

Also, seems an awful lot like a "Fishes of Florida in South Carolina" thread. 

 

Not that there's anything wrong with that!

Haha, I think the Bluefin's here in Charleston may have been introduced or at least I read that somewhere.

The "regular" brook silverside of the Mississippi basin and Great Lakes region (L. sicculus) was described in the 1800s, and in 1930 the 2nd species (L. vanhyningi) was described based on a FL population, but later ichthyologists didn't accept that one as valid until just a couple years ago when DNA evidence proved that the 1930 authors were right after all.  Both species occur in the lower Mississippi and other Gulf drainages from TX east to MS.  From Mobile Bay east through FL and up to NC we have only the southern (or golden) brook silverside.  This explains it further, including a range map:  http://www.biotaxa.o....4032.5.4/16420

The "high" eye in photos 1 and 2 is an illusion due to the angle.  Her eye is looking downward, as sunfish usually do when you hold them tilted to one side.  The dark horizontal stripe from the snout, through eye, to behind the gill cover distinguishes Banded pygmy from the other Elassoma spp in SC (evergladei, boehlkei, okatie).

Thanks I will check it out.

Interesting. I knew the silversides had been split, but hadn't seen this paper.

 

Long ago, I collected at a Prairie Creek location that is probably the 1930 vanhyningi type location. (It's a very short creek. It crosses one road.) Who knew?

 

I have 3 vanhyningi in a large community tank now. One I collected at a Ga. Pteronotropis site that Michael Wolfe pointed me to, on the way back from the Reinhardt Univ. Bioblitz, back on April 23. It hit air and survived a 5 hour drive home. So I've this freak of nature for 196 days. Which is exactly 196 days longer than any silverside had lived for me before. The other 2 have been with me for two weeks today, they came from the Tampa area. (2 of 8 survived.)

Congrats on a silverside Methuselah... I had one that was an accident from one of the Okefenkee trips that survived a cooler for days and lived here for quite a while... learned to eat flakes off the surface and competed with Pteronotropis for food.  They are very cool, but it is rare to get them settled in at home.

Does anyone know the official common name of L vanhyningi?  Is there one yet?  Also, I stocked some (northern) Brook Silversides in a pond this spring and got some reproduction.  Some adults lived in there all summer too.  Maybe a new option as alternative pond forage.

I don't know of any official common name but I have seen them referenced as Golden Silversides. Example: http://www.bioone.or...10.1654/4813s.1

I think Gerald is correct, looks like a freshwater goby from here!
