I was wondering why my 3 bluegills i have red fins. I is a darker red. They had these once they started getting their sunfish shape. I just never have seen a picture on the internet of one with red fins.

I've seen bluegills with red fins from water that was darkly tannin stained. The red was more of a rust or brick red but it was very intense in some fish.

...is it possible they're originally from peninsular Florida?

I've seen those rusty-finned bluegills in FL too, but not in NC. Also, captivity can do funny things to fish pigment. A friend in had some wild-caught sandbar shiners in a tank with spottail shiners and creek chubs. Sandbars are normally plain silver, with no obvious stripe except in small juveniles. After several months of tank life his sandbars developed a lateral stripe and dark-edged scales on the upper part of the body, obscuring the normal silvery iridescence. If I had caught them like this wild I would be hard pressed to ID them as sandbars. Maybe all bluegills have some genetic potential to make red pigment, but it's only expressed under certain conditions (water quality, water color, diet, social interactions, etc).

Most of the Coppernose Bluegill clan has reddish fins. Especially the Suwannee River system and St. Johns river system populations. Those further south and along eastern seaboard starting with Georgia have a dusky to grayish color but not the greenish typical of the Northern Bluegill populations. If a proper bluegill with reddish fins, you also see a creamy trim. Other sunfishes I have seen with reddish fins lack the trim.

They are from Florida, And they do have vertical bands, and the red is copper like or brick red. I guess they are coppernose bluegills. I know they are bluegills, I just didn't know if they are a hybrid. They are healthy and show no signs of disease.

also, i have no good cameras. My only digital one broke somehow. It didn't crack, just will not open the lens anymore.

Isaac, you are straight up awesome. I don't know how you pull these photos off, but whatever it is, keep it up.

That looks pretty much like mine. How big of a tank do they need? Also what is their total/max size?

Might see 8-10 inches in a tank. Bigger if you feed heavily, do frequent water changes, and have a large tank. A 75 would be fairly comfortable for a trio in my opinion.

Is it strange that I want to reach out and pet the Bluegill? Terribly jealous of your skills Isaac!

The reason I was asking about tank size is i might get a 120-180 gallon aquarium soon, or at least a 4-6ft length, 2ft wide tank.

I remember you mentioning this. I consider it one of the great unsolved mysteries of native fishes that needs investigation. (the other one is active vs passive winter bullheads, is their torpor influenced by size like stripers?)

It got me thinking. Do the shiners in question regularly spawn on the nests of other species? If so do they hatch at the same time as others? If so it may be an advantage to shift their color to match other similar sized minnows so as not to stand out in the school think this definately needs study. I have observed smaller/younger minnows look more similar to each other than adults and have wondered if their was a reason for this.

With respect to the pigmentation of the vertical fins in bluegill, the red versus greenish versus dusky is dominated by genetics with little environmental. We no longer have wild bred bluegill yet we can distinguish source based on fin coloration. This holds even for F2's that have never seen the sun.

THAT'S AWESOME!
Never seen one like that :wub:
Reminds me of Paretroplus from Madagascar. So sweet... thanks for sharing.
