Are there any reliable methods to determine the sex on RES outside of the spawn? Any tell-tell signs one way or another?

Steve I generally observe that females have more yellow/cream sides and bottom and are lighter than males, which are typically have more black checkering on the sides. Also the red margin on the opercular tab seems to be deeper, darker in color on males than females where it's lighter and maybe more light orange than dark red. Sexing younger fish out of spawning season for me personally is kinda a crap shoot.

Thanks TJ!

The reason I asked is that two of the five aquarium redears I have have started turning darker over the last week. Both are 18 months old and around 7-1/2".

Bingo! Right on the money!


If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.

By the way, 7.5 inches at 18 months is outstanding! Nice work, young man.

I have serious difficulty applying this ID process in reality...

I think I will stock some verified males for the trophy male BG, female YP pond this Spring. I think 15-25 RES would perform very well and keep my snails managed - limited competition could yield some impressive growth.

BTW that's amazing on your RES success...congrats!

...and redears, of course, on the left.

Top left is the female RES

Thanks Eric!

I was really hoping for something like "scale tipping" or the lack of as a good indicator of sex. Three of my aquarium RES have yellow fin tinting underneath just like the picture in your signature. The other two have dark fin tinting like the male and female RES picture you posted, they are also noticably overall darker than the other three. I think I have two males and three females but I wouldn't bet the farm on it.

To be honest with you, I've always had significant reservations about the above photo. The fish on the upper left that's designated as a female RES, looks nothing like the females I've ever seen. I've always regarded that fish as a male that simply isn't in full spawning regalia. The eartab looks very "male" to me.

Interesting, I wonder if the fin tinting underneath is indicative of sex in sexually mature RES? Females yellow, males black?

We need some definitive photos of before and after.....filleting that is.

Otherwise it all seems interpretative, without a known starting point.

Good point! To complicate matters I wonder if RES have the equivalent of "cucks" and "sneaks" like BG do? grin

Crap, hadn't thought of that...

I will put some RES under the knife next opportunity that I get, and post the definitive photos.

I'm going through my notes, but only found one photo with a positive female ID. I don't normally keep RES, but here's one where I did. Don't have any "after" photos as proof, but my records indicate the fish was filleted and verified. I will try for better photos, and before and after verification from now on. What do you think?

Tony, does the yellow color of the female stay fairly consistent year round?

I think so Al. My records show this fish was taken the last week of Feb. 2012, so It may even be a little washed out in this photo. This fish was 10", so it was mature.

Dark but yellow tinted fins underneath, I would have guessed male if the the red on the ear tab had been a lot larger.

Shorty, what all do you see? When I study the photo, I'm drawn to the eartab's lack of projection onto the body, the narrow margin with what I would call an orange border, and the creamy light yellow area on the "belly". I always considered all three of those as female RES traits.

I do catch a fair number of BG x RES hybrids, but don't recall ever having taken any females in that regard. To me, this fish displays several RES markers, but I can't rule out any BG influence in there somewhere. But, unless I'm way off on deciphering my notes, this was a female.

This a red ear electroshocked up at our place this last Spring. Male?

Definitely a male.

I dropped off a 12 inch mounted female a couple of weeks ago at a bait & tackle store, which is one of my taxidermy pick up drop off points. Anyway there was a gentleman there that saw it and commented that the ear tab wasn't red enough. I had to tell him it was a female and the ear tabs on the females are more subdued than the males.

Al that is a superb RES! And I would call it male also.

Tony thanks, but I have to admit I'm clueless about red ears. IIRC, I had a 85/15 CNBG/RES order at least 8 years ago. I was surprised to see so many because I've never caught them. I'm doing something wrong.

Female RES



I went to sleep thinking about this photo, and woke up still dwelling on it. It's listed as a female RES in my notes, but it just doesn't look right.

There's surely some BG in there.

Body shape, coloring? Just looking at the pics, it seems like the confirmed adult RES backs drop straight down behind the dorsal fin, which makes the tail look longer than a BG. Bear with me on this, I'm taking baby steps.
