Hello everyone! has any ornamental fish feeding problems, you can directly search for fish raising skills and keywords on the entire network. allows us to raise water easily and fish happily.
September and October are the season for this kind of small insect outbreak, and many aquarius have recently started to ask a lot of questions.
In fact, we have encountered this problem when I was raising goldfish in the fish pond two years ago. I have explained it a long time ago, why does any impurities under the fish pond turn into tubular things?
Then there are some small things that look like nematode ? What are these little things, are they harmful to ornamental fish?
filter cotton, bottom filter chamber, and may appear at the bottom of the fish tank
Some fish lovers found this kind of small insect on the filter cotton, red or light red, and were moving there in a curved manner.
Some aquarists found such a small thing on the bottom or part of the filter material of the bottom filter chamber, and what about it?
You often find that there are some silt-like tubular objects at the bottom of the filter chamber. Ask, what exactly is this?
is too indifferent? Don’t even recognize Redworm ?
Most of these small things are little red worms we use to feed fish.
red worms are larvae of chiropra and are one of the main groups of benthic animals in freshwater waters. There are about 5,000 known species of chiropra insects in the world, which is similar to common mosquitoes.
Red worms are cylindrical and worm-like, with slender body and two or three centimeters in total length. Some species are blood-red because of heme in body fluids.
Red worms enter the breeding period in May, June and September and October of each year. The newly hatched red insects are phototaxis. After 3 to 6 days of floating life, they turn to benthic life and use silk-like objects secreted by algae , rotten chips , fine sand, silt, and salivary gland to build nests. Most types of form tube-shaped nests with openings at both ends.
As the larvae moves into benthic, the larvae change from phototaxis to backlight.
The larvae enters the pupa stage after four molts. Each molt once, the body color deepens, from light red, bright red, and dark red to dark brown pupae.
Redworms are excellent natural baits for a variety of economic aquatic animals, important baits for economic fish, and have high nutritional value. Does
need to be cleaned? Most of them are not necessary. Cleaning up is just the routine
. First of all, these chiropractices do not bite people. Secondly, as long as they appear in the fish tank, there must be a source of seeds in it.
Because the humid environment and organic matter on the bottom filter of the fish tank or filter cotton are suitable for the survival of their larvae, they naturally come here to settle down, which is such a simple problem.
includes other small insects such as worms and red nematodes. In this season, it is possible to settle down on filter cotton and filter materials. This phenomenon is no longer surprising for veteran fish farming.
If you want to deal with it, you have to clean the filter cotton, filter material or replace it directly.
Pay attention to ensuring that the water quality in the fish tank is not as fat as it is, and the impurities do not gather too much. Want to drug it? Forget it, just give up this idea.
The main reason is that we have not developed a good habit of changing water and washing cotton in our daily lives.
To put it bluntly, it means that if the fish are raised more, the density is high, and the pollution is serious, it will attract bees and butterflies.
filter cotton can be picked up and fed to small ornamental fish. They will definitely eat it and there will be no problems.
I am a fish-raising master. Please pay attention to more ornamental fish questions, thank you!
