I was wondering if anyone could lend a hand Iding these two fish, they are being very, very hard to get a positive ID on and figured the seasoned vets at NANFA could lend a hand because I'm clueless.

This first micro fish was caught in Islamorada Floridia (Saltwater), coincidently its not the first time I saw this fish, its been caught before and not ided due to poor photos, now i have plenty, if you need more photos ask I have them!

The second fish is what you would call invasive (Freshwater), which I know is not inkeeping with the "native" theme of the site, so if nobody knows thats okay, but maybe someboy does?

I also need help on this fish, I believe it to be a warmouth, is that the case? I have multiple bad pictures of this fish, this is the best I got due to unusually high rate of mosquitos. This one was caught in the "everglades" area of Florida.

First one looks like Gnatholepis thompsoni. Second one looks like a Tilapia species. Third one is a Warmouth.

I agree with the warmouth ID also. And oh yeah, nice shirt :-)

The first one is a species of Bathygobius. There are three species in Florida and a positive ID would require checking the tongue and/or counting pectoral fin rays.

The second is an odd one -- my best guess is a very poorly marked Tilapia mariae, but I'm really not sure on that one.

Third is definitely a warmouth

Is there any way to count pectoral fins in any of the photos above? I have more than a few photos of this fish because I knew gobies are a problem I can post them later if needed hopefully I have some of that region

I know fish #2 is a juvenile tilapia mariae (good id mzokan), they are in my area by the thousands.

^{Your goby is most likely Bathygobius soporator, the frillfin goby, based on the number of dark saddles on the back with the broadest below the first dorsal fin.}

So far I've heard Goldspot Goby, Notchtongue goby, and Frillfin goby (multiple times), and Island frillfin goby. I"m pretty sure goldspot and notchtogue are incorrect. Is there a way to ID for sure from photos? I have plenty however none are of the inside of the mouth. I'm inclined to say Frillfin, but I want to be certain.

BTW thanks all above for the help its much appreciated!

In my opinion it is either a frillfin or a notchtongue, but I can't resolve enough of the pectoral rays to be certain (notchtongue has 15-18, frillfin has 20-21). Fritz may be right about the saddles. Also, frillfin is the larger of the two, if it was larger than 3 inches, then its probably a frillfin.

Judge for yourself:

frillfin: http://gobiidae.com/..._sorporator.htm
notchtongue: http://gobiidae.com/...ius_curacao.htm

If I thought I was experienced enough to judge for myself unfortunately I would have. If I had to guess I'd say frillfin, notchtoungue or island frillfin, however I've looked at these photos so many times I'm started to just give up ](*,)

here is a few more photos, maybe they'll help with a positive ID if they don't I'm throwing in the towel I'm sure me and this goby will meet another day and when I do hes getting a strip search and dental exam :blink:
