I believe that in the tank of every aquarist, there will be a large number of inexplicable small creatures ~, some of which are brought by living stones, some of which are brought on the base of corals; some are cute and cute, and some of which are abominable. But if you see some strange little creature, don't panic, don't be afraid, open this article, and look up what it really is? Beneficial or harmful?
Harmless organisms
1
Bristilla
This should be the most common hitchhiker, many people look at bristles very unhappy, because they are indeed unusual, often, ugly! But you can't just look at the value of the face! Bristles are really beneficial insects, it will clean up the remaining food residue, eat the corpses of dead creatures, and it is also a scavenger in the sea tank. There are also several kinds of bugs, which are close to the function of bridgiform worms, and are also beneficial insects.
2
Noodle worms
The biggest feature of the noodle worm is a body, and then it stretches out countless slender tentacles. Because the tentacles are too many and too long, the bug is easy to identify.
3
Peanut worms
Very common, living in living stones. If you smash the living stone open, you will find a huge number of peanut worms in the pores of the living stone.
4
Tubular worms
This mini tube worm is also very cute! When I first went to sea, I stared at a small tube worm for half an hour. Tube worms are filter-feeding organisms that can eat excess organic matter in water and purify water quality. Tube worms are abundant in the sea tank, and if you don't clean it up, you will see dense tube worms on the wall of the tank, which are like a small spiral one by one.
5
Flat jump shrimp
A small snack of fish, a mouthful of beauty.
6
Isopods
This white/yellow bug, which resembles a small ant, is an isopod worm. A lot of people have a lot of isopods in their tanks, and I have all of them in my tanks, but they're really harmless.
7
Bran shrimp
8
Snake starfish
Helpful little creature, lovely.
9
Brown flat
Although the name of brown flat is brown flat, it is not actually a flat worm in essence. I used to have very, very many brown flats, and the bugs were harmless in themselves, but if they made LPS home and multiplied in LPS, it would still be bad for corals.
One of my favorite frog eggs once parasitized thousands of brown flats. So, if your brown flat parasitizes on LPS, you still have to manage a tube.
But if your brown flat only crawls on the wall of the tank, and it is not full of mountains, in fact, you can completely ignore them.
10
sponge
These strange things with messy shapes are sponges. There are various colors, white, yellow, and red are common. Completely harmless, it is also filtered, filtering excess organic matter in the water.
11
Sea squirts
Filter feeding, filter excess organic matter in the water. Generally speaking, sea squirts have two mouths: one inlet and one outlet. The water enters through the inlet and exits, and the sea squirt filters the food in it.
12
Hair pot
White, like a small kettle, with a bulging belly. Filter feeding, purify water quality.
13
barnacle
Barnacles are actually very cute, and I have been stretching out a small claw to grasp and scratch ah~ to grab all the small foods in the water to eat. Barnacles sometimes grow on stones, sometimes on the bases of corals, and sometimes even on SPS. But it doesn't matter, they are all harmless~
14
Guqin pseudo-mouth snail
Ugly in appearance, it looks like a yellow mud snail, and it is a harmless algae-eating snail.
15
Stone turtle
It's so ugly... Harmless anyway
16
limpet
Eat algae, harmless
17
Umbelliferous algae
harmless
18
Cyclic worm algae
19 small hairy crabs on live stones
There are two kinds of small crabs, one lives on the SPS, and the SPS that gnaws on is a white spot, which is harmful and must be removed:
There is also a kind of living stone, every day after sunset, sneak out to eat debris, eat algae, eat dead small corpses. It's also a helpful scavenger:
20 small hydra
21 small snails
Filter feeding, harmless
22 small snail algae
Tanks that often multiply are full, but they are not harmless
Pest !!!
Mantis shrimp
Mantis shrimp with its anti-natural attack power, firmly topped the list of pests. It can be described as the ultimate killer in the living stone... You can kill all the fish, shrimp, crabs, snails, shellfish that are smaller than him, and if you don't know the strength of the mantis shrimp, you can search for videos of mantis shrimp eating crabs. The elasticity and attack power of the arms are amazing. I also have a mantis shrimp with a little thumb in my tank, and Missy has dropped two ghost kings and a leopard dragon... After there are no small fish, it also preys on the algae snails and bullseye snails in my tank. Eat an average of 1-2 bull's eye snails a week
Gun shrimp
Living in the holes of living stones, he rarely goes out, but every day he will wave his big pliers and hunt "snapping". If you can often hear the sound of "popping" in the tank, then half of it is a shrimp grab. Both gun shrimp and mantis shrimp can make a "snapping" sound. But the gun shrimp is more frequent, sometimes within a few minutes can be connected to the "popping", while the mantis shrimp is more quiet, occasionally only a snap... Gun shrimp are theoretically hunted for small fish, so they are classified as pests. But in fact, their attack power is very limited, at most they can only hunt super small fish, so they are not small creatures that must be killed ~ not to mention... Even if you want to kill, you can't catch it.........
Sea Hare
There are also hundreds of species of sea hares, some of which are harmless to eat algae, and some of which feed on corals. For example, in the red circle above, the green sea hare is the classic button-eating sea hare. If you see a sea hare in the tank, it's better to dispose of it just in case.
Large worm snails
The large worm snail lives on living stones, it has a mouth cover, two tiny antennae, and the most important feature: it spits silk. The snail itself is not harmless, but when there is a lot of debris in the water, it spits out silk and weaves webs, catching food in the water like a spider. If these nets touch the coral, sometimes affect the state of the coral. In addition, in fact, there is no real harm in the large worm snail. If you want to get rid of them, use Aaron Hair Gel to plug the hole in the snail and do it.
Garbage Aoi, Ghost Hand
In fact, there is no real harm in these goods, but because they are too skinny and super fertile, they sometimes breed in full tanks. That's its only drawback. A small amount of garbage sunflower, you can take a syringe, pour into concentrated saline, inject it to kill. A large number of garbage sunflowers can be eaten with mint shrimp or three rockets. If it's too much – I suggest you throw away the living stone.........
Bobbitt worm
In recent years, there have always been a lot of hunting news reports on Bobbitt bugs, huge Bobbitt bugs hunting tanks for everything that is alive... But don't worry too much, because the probability of having a Bobbit in your tank is similar to winning the lottery. I have seen countless open cylinders, but there are really Bobbitt worms, so far I have only seen two cases, so I really don't have to worry too much. Bobbitt worms are generally very large and long, and those few centimeters in your tank are actually bristles ~ it's okay ~ ~

Have you ever encountered these little creatures that secretly "rubbed the car" when you opened the cylinder? Which ones, and in the end did you clean it up or did you welcome their presence?
