Florida flag fish for algae control?

One day I upped my white LED lights to 100% from a fairly low level (45-50%). I forgot about it and left it at 100% for a while. Now I'm experiencing some algae problems. In addition to turning down the lights, I am doing frequent water changes and am watching my feeding so I don't overfeed.

But I was wondering: How effective are Florida flag fish at removing algae? Are they aggressive? I've read some unflattering things about their behavior, but an wondering what you all think.

I have six rainbow darters, eight southern redbelly dace and a small school of mixed shiners. I wouldn't want to add anything that would harm them.

Stonerollers are good algae eaters and would compliment what you have as they are often cohabitat species.

Depends in part on the kinds of algae you have.  Even algae-eating specialists don't eat all kinds of algae.  I haven't found any animal that reliably eats mat-forming blue-greens (Oscillatoria, Phormidium, etc).  Amano shrimp (Asian) seem to be the best overall algae-eaters.

I would go with Stonerollers, like Casper said.  They are the only native I've seen to actively eat on algae.

My stonerollers would rather eat flake or bloodworms though I see them pick at algae a bit. i would not expect them alone to keep a tank looking pristine if you have a major algae problem. The best option for that is a non native pleco such as a bristlenose imo.

Search using hydrogen peroxide for algae. I would prefer a fish do the work, but to initially get in check, a H2O2 dose might get
ahead of the game. Nativeplanter, Laura was her name, was a big proponent of peroxide for algae control. Or just learn to love it if it
isn't too out of hand.
