is that really the smallest fresh water fish in NA?
Feb 16, 2017 - Do you know what the world's smallest freshwater and saltwater fishes are
The kuhli loach (Pangio kuhlii) is a small eel-like freshwater fish belonging to the loach family (Cobitidae). It originates in Indonesia and the Malay Peninsula. This snake-like creature is very slender and nocturnal. This fish have a maximum length of 4 inches (10 cm) and can live for 10+ years, sometimes up to 60+.
I have a 6,000 gallon freshwater tank with a spectacled caiman. What algae eater could I get that won’t be eaten by the caiman? I’ve tried everything, from plecos, 100 oto catfish, 100 chinese algae eaters, and even a small phillipino boy. Sadly, none of them were able to clean the algae in the tank without being eaten! What should I doooooooo????
Smallest Freshwater Fish Species
Whats the smallest fresh water fish you can think of
February 3, 2006It could not have been easy to see the tiny swimmer, but a group of scientists claim to have discovered the world's tiniest fish. The little creature was found recently in an Indonesian swamp. For now, the fish is known as Paedocypris progenetica. It has a transparent, or see-through, body. Its head doesn't have a skeleton, leaving its brain vulnerable to its surroundings. The fish, which is female, can grow to be only 7.9 millimeters or (0.31 inches) long, about the size of a large mosquito.
Maurice Kottelat, a fish expert from Sweden, led the team of researchers that made the discovery. Kottelat and his team reported their discovery in the Proceedings of the Royal Society, a British scientific journal.
"You don't wake up in the morning and think 'today we will find the smallest fish in the world,'" said Kottelat in an interview. He and his team were most excited by the possibility of having discovered the world's smallest vertebrate, an animal with a backbone. "What's important is finding a complete vertebrae [backbone] in a body so small," said Kottelat. All fish, reptiles, amphibians, birds, and mammals (including humans) are vertebrates.
A "Little" Competition
It wasn't long after Kottelat's announcement that another researcher challenged the claim with a discovery of his own. Fish expert Ted Pietsch, a researcher at the University of Washington, says that he has discovered a fish that is smaller than Kottelat's discovery.
According to Pietsch, the male Photocorynus spiniceps is a tiny ocean fish measuring only about a quarter inch. That statistic would actually make Pietsch's fish the world's smallest vertebrate. Kottelat's would come in at a close second
When Pietsch got in touch with Kottelat to mention the fish—four of which he keeps in his office—Kottelat did not argue. He kindly gave the title of "world's smallest vertebrate" over to Pietsch's unique fish.
"So our little fish is only the smallest freshwater vertebrate," Kottelat wrote. "Now I wait until the next smallest fish is discovered." If you have decided that you are going to start with the small freshwater fish tank, you also need to decide whether it is going to be a heated fish tank or the cold water tank. Deciding on the type of tank will determine what kind of fish you can have because each fish has their requirements when it comes to water temperature. Just because they are all fish, it doesn’t mean that they can live in the same water. Some fish are okay with cold water while some can only live in warm water. Make sure to determine this factor before you can choose the right fish for small tanks.
