Planarians: Representative animals of the Phylum Platyhelminthes Turbellaria. Planaria refers to the genus Planaria, while the term planarian refers to animals of the family Planariidae and related families. Planarians live under stones in freshwater streams and feed on live or dead worms, crustaceans, and insect larvae.
【Two common planarian worms】:
The first
This kind of planarian worm is commonly known as triangular planarian, carnivorous is relatively strong, like to eat meat food, will attack the juvenile shrimp, even attack the egg-holding mother shrimp when hungry, the sick shrimp old shrimp, the shrimp when dehulled. Once the shrimp encounters this planarian, it will be paralyzed by the secreted venom and then left to be slaughtered. This planarian is also very sensitive to meat feed, and after feeding, it even grabs food with shrimp (can drive away adult shrimp and enjoy exclusive food), so it is a very good trap planarian. Due to its aggressive and carnivorous nature, it is a pest that needs to be controlled by shrimp tanks.
The second kind
This kind of planarian we commonly known as flat-angled planarians, but in fact, flat-horned planarians have other people, but the names of aquarists in order to distinguish them from triangular planarians, Taiwan calls it small planarians, in fact, small planarians are more appropriate, because of its small size, I have almost never seen more than 1cm, the common 0.6, 0 .8cm is already very large. This planarian is very difficult to trap because it is less sensitive to meaty things than triangular planarians. It mainly eats microorganisms and organic matter in the subsoil, occasionally attacks protein punches, snails, etc., and does much less damage to shrimp than planarians.
【Planarian control】:
There are 3 main sources of planarians, water weeds brought in, tap water, and mud.
Crystal shrimp tank, few people directly put into tap water, so the harm of tap water can be ignored. To prevent planarians, or the old method, the quarantine of aquatic plants entering the tank and the CO2 aeration at the beginning of the opening of the cylinder. Kill planarians by reducing oxygen levels. In any case, the emergence of planarians can almost be said to be inevitable, and there is no need to panic too much when encountered, and it is necessary to be convinced that whether the crystal shrimp can burst the tank has little to do with planarians.
First of all, there is no need to be too alarmed when seeing planarians, because almost all the grass tanks and shrimp tanks have encountered planarians, and even in the current tanks. There are many examples of planarians and shrimp bursting into the tank together, so in addition to the scary appearance of planarians, the real threat is much smaller than you might expect. Secondly, it is necessary to distinguish clearly which kind of planarians in the shrimp tank are, and the right medicine can be prescribed.
I need to emphasize again that the shrimp tank can not be drugged, and the currently known domestic masters have not yet had any examples of drugging in the shrimp tank. Because the toxicity of the drug is long-term, it will even affect the development of the ovaries of the female shrimp and cause sterilization. What intestinal worms clear, Cong Xi planarian killer, bio, panda, red bee planarian zero, no matter which of the above, shrimp or direct poisoning, or long-term chronic poisoning.
Therefore, planarians can only control their numbers, and do not want to cure them too much. What we need is a long needle tube and a planarian trap box. Triangular planarians, trapping can basically control the number of well, flat-angled planarians, trapping is almost ineffective, so it is necessary to use a needle for long-term extraction, to work hard, two methods can be used at the same time, insisting on 1-2 weeks will have obvious effects.
