Tubifex Worms – Culturing And 2 Weird Reproduction System
Tubifex worms are usually used as live food for fishes, particularly tropical fish and some specific freshwater types. Almost since its inception, they have actually been a popular food for fish tank trade, and collecting them from open sewers for this function was very common until lately.
Tubifex worms are a cosmopolitan genus of tubificid annelids that lives in the sediments of lakes, rivers, and periodically sewer lines. A minimum of 13 types of Tubifex has actually been identified, with the specific number not certain, as the types are not quickly distinguishable from each other.
Reproduction of tubifex worms
Tubifex worms are hermaphroditic in nature, that is, it has both male (testes) and female (ovaries) organs together on its single body. These minute reproductive organs are connected to the forward side of the body wall in the celomic cavity.
In fully-grown specimens, the reproductive organs are plainly found on the forward side of the body.
Copulation and cocoon formation in tubifex worms
Though tubifex worms are hermaphrodites, the male and female organs mature differently; therefore self-fertilization is prevented, and cross-fertilization is promoted.
2 fully grown Tubifex worms go through copulation by joining anterior and ventral surfaces together with their anterior ends pointing opposite directions. Hence, the spermathecal opening of each worm is nearer to the male apertures of another worm. The penial setae of one worm penetrate into the tissues of other worms and hence the conjugants are held together.
At this phase, the sperm of one worm entered the spermathecae of the other worm. And after copulation, they separate and then start to produce egg cases including eggs, called cocoons.
The cocoon is formed around the clitellum as a soft, box-like structure into which the sperm and the ova are transferred. Quickly, the Tubifex worm withdraws its body from the egg case by its backward wriggling motions.
Culturing Tubifex worms
Tubifex worms are raised commercially, generally to be used as fish food. The reddish Tubifex tubifex. Tubifex can be quickly cultured on a mass scale in containers with 50 to 75 mm thick pond mud at the bottom, mixed with decomposing vegetable matter and masses of bread and bran.
Constant, moderate water flow must be maintained in the tank with an appropriate drain system. After the system has been perfectly arranged, the container is then inoculated with Tubifex worms which can be gotten from close-by muddy canals or sewage canals.
Within 15 days, clusters of worms are developed and they can then be removed with mud in masses. The worms are gathered and cleaned under a vigorous stream of water to remove residual mud connected to their bodies when they come to the surface due to the absence of oxygen.
How to grow tubifex worms at home?
Based upon the growing conditions of tubifex worms that is required, the following are needed by the culture setup:
- Shallow Container to host the worms.
- Clean cold water.
- Pump to create the flow of water.
- Holder Container to gather and pump water back.
- Substrate or media to hold onto by the worms.
- Feed for the worms.
Tubifex as a live food
Tubifex worms are typically used as live food for fish, specifically tropical fish and specific other freshwater types. They have actually been a popular food for the fish tank trade practically considering that its creation, and collecting them from open drains for this function was rather typical up until just recently.
A lot of them are now commercially acquired from the effluent of fish hatcheries, or from expert worm farms.
Using these worms as live food has actually caused certain issues for many years. When collected from drains, open bodies of water, and even from hatcheries, they might be contaminated with different diseases.
This risk can be partly resolved by keeping the worms under vigorously running water up until they have actually voided the contents of their digestion systems.
Still, the worms can still be vectors for whirling diseases, which can badly affect salmonids. In addition, they are extremely hard for some fish to get in the wild, so specific fish, such as Rift Valley cichlids, will fanatically eat them up until cause sickness for themself.
Furthermore, while the worms have good-quality proteins, they likewise are really fattening, and are poor in particular crucial amino acids.
Fish fed on them can increase rapidly, however they might be less vibrant and healthy than fish with more well-balanced diet plans.
Finally, in a dirty fish tank, Tubifex can end up being developed as an insect type, covering the bottom of the fish tank in a thick carpet which might be considered.
Are tubifex worms harmful?
A brand-new research study of tubifex worms has actually highlighted their possibility to cause harmful diseases. These oligochaete worms, which are typically gathered from sewage-contaminated mud, are a popular food for specific tropical fish. … It is believed that their usage has the potential of spreading diseases to new areas.
Are tubifex worms great for fish?

How quickly do tubifex worms grow?
The worm grows rapidly (7.5 mg in 42 days) on a substrate consisting of 75% cow dung and 25% fine sand; the culture system (150 × 15 × 15 cm) needs constant running water at the rate of 250 ml per minutes.
How do you keep tubifex worms alive?
All u need to do is to put tubifex worms in a pail of water half full, perform water change frequently & likewise strong air bubble.
Tubifex worms normally experience high death rates and need regular cleaning to avoid decaying and harmful bacteria growth.
To clean, simply run the worms under tap water. The dead worms will sink much slower than the healthy worms, for this reason, put away the excess water 2 to 3 seconds after every rinse.
Do guppies also eat tubifex worms?
While guppies will eat them enthusiastically, tubifex worms often include deadly germs. Live daphnia will just trigger damage in big amounts by de-oxygenating the tank, however, they are usually more challenging and pricey to raise than other live foods.
Are tubifex worms parasites?
The whirling disease parasite has a two-host life process, rotating in between a little worm and a fish. The worm host of the parasite is called Tubifex tubifex.
