What is a Twig Catfish?
The Farlowella acus is a member of the twig catfish family. The twig catfish family is a smaller subspecies of the armored catfish family. It displays the same armor that this fish family is known for, but it has an extremely skinny body. That skinny body is where the fish gets its name from. It is often called the twig catfish because it is shaped like a twig. The name of this species means pointed or needle. Overall, there are a little over 35 species of this catfish. They are found in both nature and freshwater aquariums. Often, the fisherman does not fish for this family as there is little profit and the meat is not usually eaten due to their small size.
Characteristics
This fish family is known for its slender body. It is so skinny that it definitely stands out from other fish, but it will only grow to approximately six inches long. These fish can be found in a dark green or yellow color, making them a nice addition to an aquarium that already has a tropical fish community. They will blend in with plants, add a splash of color to bland aquariums and use their color in the wild as camouflage to protect them from predators.
In Nature
Twig catfish are commonly found in the riverbanks of the Torito river where the water is slow and the temperature is warm. These freshwater fish are common in South America, but not found in many other places in nature. They tend to prefer slow-moving rivers or streams and are often found feeding on vegetable matter or plants along the sides or bottom of the river.
In Captivity
These fish remain a popular choice for aquarists for a variety of reasons. They are known for their peaceful nature as they will not attack other fish. Owners should note that they also will not compete with other fish for food, so it is important to make sure that there is plenty of food available to ensure that they get their fill as well. Often, owners feed twig catfish cucumbers, sinking pellets and a bit of brine shrimp.
Although the Farlowella acus is typically a bottom-dwelling fish (hence the need for sinking pellets), it is a sociable fish. It will be found swimming in schools and enjoys the company of other fish. Aquarium owners can keep one of these fish, but they are often not happy unless they are kept in numbers of at least three.
It is equally vital for aquarium owners to be aware of how fragile the twig catfish is in nature. One fight with another fish can be fatal for the Farlowella acus, so it is essential that they are not kept with aggressive fish that could attack them. Fish owners are encouraged to keep these fish in thriving communities of fish that are equally sociable and peaceful.
The Farlowella acus fish remains one of the most popular fish in captivity. It is beautiful, peaceful and has a certain elegance that aquarists enjoy.
