If the water stays not too hot, and not too cool, you likely will find exotic fish. Fish may be less obvious, but look in the warm water, and youll see discarded animals.
Ill fish anywhere and pleasure in discovering fish in unusual places. In Florida, where the fish swim easily through the linked Everglades waters, there could be significant impacts on the native fish. And now I fish for tropical fish, too.
The Disconnect
Naturally, setting an animal free is reckless and often cruel (most animals will starve or deal with an undesirable end in the wild). What is the conservation impact of tropical fish?
That can be difficult to determine. In Florida, where the fish swim easily through the connected Everglades waters, there could be significant effects on the native fish. In a separated Rocky Mountain warm spring, the impacts are most likely unimportant. The surrounding creeks and rivers are fed by melting snow, making them really cold the majority of the year. Any fish wandering off outside the springs would fail.
Barney Hot Springs lies about as far off the beaten course as you can get in southcentral Idaho, hours from the nearby considerable town. I went to there with a fly rod in 2016, capturing Mozambique tilapia, zebra mbuna and found guilty cichlid. These three tropical types had actually been documented in Barney for years.

That winter season, an ice dam had actually blocked the local river, causing it to flood Barney– and cleaning out the fish. When I initially fished there, I d sometimes see a skittish goldfish among the cichlids.
Ive heard from recent visitors that other fish are beginning to reappear in Barney. Possibly someone has actually discarded brand-new fish in there.
But in other instances, there is concern that non-native fish might spread out from the springs to linked waters. A warm springs in Grand Teton National Park was widely known for its populations of non-native convict cichilds, guppies, green swordtails and tadpole madtoms, frequently compared to a national forest fish tank.
Park biologists found that the unique types were getting extremely close to the close-by Snake River, from which they had almost endless opportunities to spread out. In 2018, managers treated the spring with rotenone to get rid of the non-native fish, hoping that native fish would recolonize the waters.
I went to in 2020, fishing rod in hand. I immediately started catching Utah chubs and redside black eyes, a hopeful indication as both are native types. However then I hooked a convict cichlid, and another. Had they made it through the fish obliteration, or had they been just recently released? It is hard to know. The human capability to play appears endless. I think of an endless cycle of exotic fish, going and coming, through no fault of their own.
Fishy Values
In the clear, blue waters, numerous participants had seen weird fish. They contend with the native fish, like bass.”
By state guideline, any Nile tilapia captured has to be killed. No catch and release for them.
But the bass are no more belonging to Utah than the tilapia. Largemouth and smallmouth bass– and a host of other “game” types– have actually been presented far and wide. While the cichlids might have been disposed unlawfully by animal owners, the bass have actually been equipped en masse by state wildlife agencies, typically with fanfare and extensive support.

I publish a photo of the bright-orange red devil cichlid on social networks, and Ill get remarks about how horrible this is for the environment. And yes, any non-native types is a possible issue. The red devil looks so exotic. However in the American West, its not going far.
Its rare to cast in any water, consisting of free-flowing rivers, and escape the presence of non-native game fish. And now I fish for tropical fish, too.
Simply today, I received a message from a fish enthusiast who reported capturing some odd cichlids on flies in the regional river. Ill continue to work to save and bring back native fish with an enthusiasm.
Im on a quest to catch a fish in each of the 50 U.S. states– and to utilize each experience as a method to check out preservation, the most recent fisheries research study and our complex connections to the natural world.
Im drawn to wilderness warm springs, but not for the factor you believe. Im not here for the soak. Im here for the fish.
The blue, clear waters sparkled before me, bringing to mind the Caribbean. And certainly, the other day a group of scuba divers appeared and disappeared along the surface area, calling out instructions to each other. Today, I had the location to myself. I was in the middle of the Utah desert, at a 10-acre lake down miles of bumpy, dirty roadway. And I had a fishing rod.
The lake is called a trophy largemouth bass fishery. The other day, I caught a few of those bass, although they werent my target. Today, I chose to inspect out a few of the wetlands and smaller sized lakes that ringed the main one.
As I strolled along the desert waters, I spotted a swirl of fish. I squeezed a little split shot onto my ultralight line, rigged a maggot and flicked it out. Barely had my bait struck the water when the surface sprinkled and my line tightened. I reeled and rapidly saw it was no largemouth bass. The markings on its sides gave it a zebra-like appearance, although this fish is commonly called the giraffe cichlid. It is native to Lake Malawi in southern Africa. Now it is also found in the middle of the Utah desert.
The cichlids were hungry. After a couple of fish, I captured a fully grown giraffe cichlid, with a brilliant blue head and yellow sides with black mottling. It was also one of the most beautiful fish Ive ever captured.
Not Too Hot, Not Too Cold
I enjoy a soak in warm water as much as the next person. Ive seen some of my worst displays of mankind at hot springs.
Reports of fish have actually led me on wild goose chases after and have had me casting lines in the strangest of places. Because, frequently, where you have warm water, you have exotic fish.

The most obvious example is South Florida, where a cast into a canal may land you a Mayan cichlid from Central America, a peacock bass from the Amazon or a walking catfish from Southeast Asia. There are clown knifefish and jaguar guapote and eastern happies. Recently, the “river beasts” referred to as arapaima were documented. For anyone who follows invasive species concerns, this is not unexpected.
Tropical fish in North America are kind of like Goldilocks. If the water stays not too hot, and not too cool, you likely will discover exotic fish. Its also true of hot springs found in relatively beautiful national parks and national forests.
Many hot springs are too hot for fish to eke out a living. These are where you find the fish.
The fish are as much an artifact of human misdeed as the discarded beer cans you often discover at such locations. People get tired of family pets. They set them complimentary. This is why parrots fly around Los Angeles, pythons demolish Everglades wildlife and stray felines stalk your bird feeder. Fish may be less obvious, however search in the warm water, and youll see disposed of animals.
I love and value native fish, of course. Ill fish anywhere and delight in finding fish in offbeat locations. What will I discover in the warm spring?
