“Yeah, I know we’ve posted several times with these Pygmy Sculpins,” writes the social-media manager of the Conservation Fisheries Facebook page, “but they’re just so stinking cute!”

For those not already familiar, Conservation Fisheries is a 501(c)3 non-profit organization based in Knoxville, Tennessee. The organization was founded by Pat Rakes and J.R. Schute and “has partnered with many federal and state agencies, conservation organizations, and private individuals to increase our ecological knowledge for more than 60 species of rare and under-appreciated southeastern freshwater fishes. With their partners, their efforts have contributed to the improved status of many, with the eventual goal of removal from Endangered Species Act protection seeming closer to reality. For other species, their pro-active projects, with partner support, likely prevented the need for federal endangered species listing.”

In this recent video, Conservation Fisheries highlighted their ongoing work with the threatened Pygmy Sculpin, Cottus paulus, and they’re just downright captivating. We challenge any aquarist to find fault in these charming, bumble-bee-colored North American natives that put on quite the show for viewers!

“Notice the color variations. The ones with black heads are nest-guarding males. All of these are second-generation fish.

“This tiny sculpin is found in a single spring in north Alabama. They are extremely sensitive to temperature fluctuations. Their eggs are especially sensitive to temperatures either higher or lower than their preferred narrow range. A recent presentation by Rachel Moore and Carol Johnston noted that the temperature of the spring has risen several degrees since the 1970s. It remains to be seen how this might affect these little fishes. Will they adapt?”

      100% agreed! Entire team seems very motivated, invested, and dedicated! Maybe we should interview them for a future issue of AMAZONAS?
