Dustin,
Did you happen to get any pictures of rainwater killie? I'm trying to get some new, high quality pictures of fish we rarely see in our work and rainwarter is one of them.
Yeah, the rainwater did not want to cooperate. I have some here so I am going to try to reshoot them. I also have a decent shot of a female.

I have a few questions, if you have the time;
How do you get the fish to flair their fins for the photos?
Was the mollie a full size mature adult? Did you see any males with larger "sails"?
What habitat were you collecting in? I assume brackish by the sheepshead, mollies and rainwater. Were the other species found in the same habitat?
Did you happen to get any fired up male rainwaters, and if so were they lemon yellow?
Matt, I have a small colony of rainwaters going and have had some moderate success breeding them. I've been working on getting some pics. None I've got so far are worth sharing but once I get motivated, I should have something interesting.
IMO, rainwaters are highly under rated and once I post some pics of fired up lemon yellow males, I expect people to get interested in them.

In the marine tank they are the only schooling fish [a butterfly and flounder are the only other inhabitants]. There, the males stay colored up 100% of the time, guard territories and display constantly.
In the freshwater tank, they are part of large mixed school of sailfin mollies and flagfish. Those males are a much paler, less flamboyent yellow color, do not attempt to guard territories and rarely display. They do still spawn however and if rescued, the eggs hatch and fry develop normally in the freshwater.
Both groups apparently hunt down and eat fry as only fry I rescue or that get sucked into the canister filter survive.
I'm not sure if the color and behavoir are different because of the salt/fresh water, and/or the type of community setting.
Edited to add: Feeding is different between the two communities as the butterfly and flounder get large quantities of meat, mostly saltwater mussels, which the killies stay fat on. Because the mollies and flagfish graze algae, meaty food is only offered a few times a week. This could potentially influence the behavoir and color differences in the killies as well.

Hey Dustin, great photos! Did you attempt to find banded sunfish? Also, do you mind PMing me your approximate location for the lined topminnow, I was never able to find any in the Charleston area.

We didn't look for the bandeds this time, but we did the last time, about 2 months ago. We searched all around those forest roads and hit all the spots you suggested with no luck. We actually only caught 1 spotted sunfish the entire time we were back in there. I suspect that many of the streams and holes had dried up in the drought and were just refilled with the rains we had had then.
Yeah, most of those streams dry down to nothing and the best time is when they are drying up. Even under the best conditions I rarely caught large numbers of fish in those creeks. It seems that they have very low productivity and just don't support large fish populations.
