![]() If one end of the critter in your aquarium is on the glass while the other is in the water and has multiple tentacles, it is a hydra.The swimming movement of leeches in water is wiggly. The name given to the movement of leeches is “looping.” This means that they attach the alternate ends of their bodies to the tank wall – head attaches, the tail moves up, tail attaches, the head moves forward, and so on. The pest in the aquarium is one of the species of leeches if part of their body is moving in the water and the other part is latched onto the aquarium glass.Worms under this category (flatworms) are usually flat and wide in shape and they don’t usually curve their heads often. Some of the worms in this category include planaria (with a head shaped like an arrow) or rhabdocoelas (their heads are round). For flatworms, their bodies are latched onto the glass and they keep moving although their movements are slow like that of a snail.These worms are long and thin in shape, they usually curve their bodies and they don’t typically have ahead. Detritus worms fall under the group of worms called Annelida (tubeworms). If the movement of the entire body of the creature is jerky or it appears that the worms are dashing along with the glass or on the water surface in a snakelike motion, the pest is most likely a detritus worm.If there are creatures that look like worms moving along the glass in your aquarium, you can detect what kinds of creatures they are by the way they move: There is another kind which is called freshwater limpets – they are ramshorn snails of the genus Ferris and the Planorbidae family which means that they are not limpets. LimpetsĮvery snail whose shell is flat – appearing like one-half the shell of a clamp – falls under the group known as “limpets” whether they are closely related or not. The difference is that unlike bloodworms, they don’t have distinct heads neither do they have legs. This is because their blood contains hemoglobin and they are bright in color. Sometimes, certain detritus worms (annelida) are thought of as bloodworms. NOTE: Bloodworms’ problem is that they could be mixed in with hydra and planaria which can wreak havoc in the tank. Fenbendazole and copper are usually not used to get rid of snails in a tank (aquarium) because the dose of those two is not strong enough to get the job done. It is important to know that before critters such as snails, invertebrates, and shrimp, you must increase the dose of the medication you want to use. Tubeworms (Annelida) TubewormsĮxamples of tubeworms include snail leeches, leeches, and detritus worms. Roundworms (Nematoda) Roundworms (Nematoda)Ĭamallanus and capillaria fall under the group nematoda. The worms that fall under this group are the rhabdocoelas, planaria, and flukes. Flatworms (Cestoda and Trematoda) Flatworms There are four groups in total – three worm groups and a hydra group. Wormsīefore talking about the various medicines to deal with worms, let us first examine the groups of worms. NOTE: When people talk about aquarium ‘worms,’ the next thing that follows is a conversation about ‘ dewormers’ to either remove or prevent them from entering the aquarium. They look like gliding worms that crawl along with the glass of the aquarium. Planaria and rhabdocoelas are other kinds of critters that can be found in aquariums. Another factor that can increase their number in a tank is when it is too large. When discus fishes are overfed, these critters tend to increase in number by a large magnitude. One can find detritus worms in almost any aquarium. These critters are not worms in the strictest sense of the word, in fact, they are in closes relation to anemones. When the creature found in the aquarium water has a lot of arms with its head, it is a hydra. Limpets Critters (Most Common Aquarium Pests) Hydra Hydra.Medication for pests Pests & Worms Categories.Just like every other snail, they do not cause any harm and they can be controlled with copper – in an aquarium, copper can be used to kill invertebrates. NOTE: Oftentimes, discus breeders find a large number of gastropods on the glass of their aquariums. Color & Appearance Issues Submenu Toggle.
