What Is a Pom Pom Crab?
Pom pom crab is a crustacean that inhabits warm water. They usually have in their claws two little sea anemones. These anemones resemble pomp balls shaped like fluffy balls. They are transported anywhere by the crab since they assist in defence and food collecting. Several individuals love seeing such an act, as it is intelligent and cute. A crab in the form of a pom pom remains small, that is, approximately one inch in size. Pom pom crab is small with a cute anemone, which makes them popular with nano aquariums. They are timid in the daytime but very active at night. They are peaceful in nature and hence suitable in peaceful tank environments.
What Do Pom Pom Crabs Mean? (Meaning and Peculiarities)
Pom pons crabs are named after the anemones, which resemble pompoms. These anemones assist them in trapping tiny particles floating in the water, hence they catch food. You will see, too, that the crab jerks them around when in danger. Such actions frighten other smaller predators due to the anemone’s sting. This strange alliance of nature being demonstrated is adored by many hobbyists alike because it demonstrates how nature makes intelligent alliances. The anemones provide the crab with a feeling of motion and protection, which in turn allows the crab to eat and defend itself.
Their peaceful personality is another interesting feature. Pom pom crabs do not cause trouble, and they hardly attack other tank mates. When they are in a stressful state or when they do not know much about what is going on, they will favor hiding under rocks or plants. They will be digging small tunnels when they explore or moving gravel about. They remain soft in their ways and bring minimal inconveniences. They are also used to clean small particles of residual food, which, in a way, enhances the hygiene of the tanks. Owners attach them to the tanks as a lot of them believe they are great additions that remain interesting without raising expenses on tank maintenance.

Are Pom Pom Crabs Freshwater or Saltwater?
Pompon crabs that are kept in domestic aquariums are typically freshwater creatures. They originate in the slow rivers and the serene lakes of Southeast Asia. Such waters are organized, stable, and not hot, and it is easy to take care of them in tanks. They are fond of moderate filtration water with a mild shower. Do not use strong currents since such crabs may not be able to cope with quickly running water. They can climb up and down surfaces; hence, you should keep the tank covered.
It also has a saltwater alternative that occurs in the ocean, which, however, is not the same as that which is sold in shops. The majority of the hobbyists retain the freshwater forms because they remain healthy and non-aggressive in small tanks. Whenever you purchase a pom pom crab, look at the label just to be sure that you are dealing with freshwater or marine. Being kept together in the wrong kind of setting may result in stress and premature demise.
The Freshwater Pom Pom Crabs
The freshwater pom pom crabs keep company with various non-aggressive fish. Marine pom pom crabs also have a different lifestyle, and they are frequently added to the reef tanks. The marine pom pom crabs may be harmless to reef constructions since they do not cause much damage to the corals. Mostly, they move around the rocks and shake their anemones as they feed on microfauna. In the case you maintain the marine version, make sure that you have ample rock formations and constant water levels in your tank.
With fresh water crabs, maintain a constant temperature at 75-82 deg F. They have places to conceal themselves, such as caves, plants, or rock crevices. These crabs cannot survive properly out of water; hence, never keep them in paludariums. Use a safe lid and do not use copper-based medication since the crustaceans are killed by copper. With the right care, pom pom crabs live peacefully and stay active for several years.
Are Pom Pom Crabs Okay with Hermit Crabs?
What can live with a pom pom crab? It is possible to have pom pom crabs that are kept with hermit crabs. Hermit crabs are typically found in marine environments. Thus, the mating is used on saltwater pom pom crabs. Hermit crabs do not attack unless hungry or competing over space. Pom pom crabs are harmless, and they like to hide in the spots, instead of in the open. Due to this nature, there is no significant issue that can make both species coexist in the same environment.

Pom Pom Crabs with Hermit Crabs
During the initial days, you should see them too. When searching for new shells or food, hermit crabs are sometimes aggressive in their exploring. Pom pom crabs might use waving of anemones as a defensive mechanism, yet they do not fight often. When the hermit crab is too inquisitive, he may drop the idea with a mild sting from the anemone. Such minor interactions tend to calm down easily.
Make sure there are sufficient concealment spaces and abundant food supplies for all tankers. Both species would be fed at the same time, thereby reducing competition. Marine pom pom crabs tend to remain near crevices of the rocks, whereas hermit crabs mainly move on the substrate. This is what separates them and contributes to the peaceful state of the tank.
The freshwater hermit crabs are scarce, and thus, a mixture between freshwater hermit crabs and freshwater pom pom crabs rarely occurs. Whenever you attempt such a pairing in the future, ensure that both species have similar needs of the environment. Always consider tank size, water type, and temperature when selecting tank mates.
Thoughts on Pom Pom Crabs to Keep Them at Home
1. An Enjoyable Experience
It is also fun to keep pom pom crabs in the house as they remain lively and calm. You need not worry and watch them flutter their anemones and roam about the tank. They do not require very big aquariums, hence a small, well-kept tank is good. But then they also need many places to hide since they like their privacy. Driftwood, caves, stones, or thick vegetation can be used to produce areas of comfortable shelter.
2. They Like Clean Water
Clean the waters with stable conditions like pom pom crabs do. Add a little water every week to ensure quality is good. It is important not to subject them to abrupt changes in temperature since they are stressful. You may not have to see them every hour, but they like to conceal themselves in the daytime. At night, they are livelier when there is light shadowing.

3. Feed them Mix
Offer them sinking pellets, flakes, or little frozen foods. They also dine on bits of leftovers that remain around, and these aid in making the substrate cleaner. Avoid feeding too much since food that is not consumed falls and pollutes the water quickly. Give a little food one or two times a day according to tank size.
4. Provide Enough Space
When keeping several pom pom crabs, make sure that they have enough space. They normally allow each other, though when in a crowded area, territorial behavior may manifest itself. The relaxed tank sitting will minimize the stress and make them social. You do not have to deal with aggression, and you can enjoy watching them play with their surroundings.
What Can Live with Pom Pom Crabs?
Pompon crabs are compatible with species of peaceful life in freshwater and marine systems. Small fishes such as guppies, mollies, neon tetra, and rasboras are the ones that thrive with freshwater crabs. These fish do not trouble the crab and are fast enough not to cause misunderstanding. The shrimps do not mind having pom pom crabs, particularly cherry shrimp or the Amano shrimp. Both species are similar in other aspects, such as water preferences, as well as in the cleaning of small particles.
Pom pom crabs should not be kept with big or violent-looking fish. They may be bullied or consumed by species such as cichlids, large barbs, or predator fish. The crab may also become trapped and become targets of slow fish with long fins. Small snails or such placid bottom creatures as kuhli loaches or otocinclus also do well. They never intrude into the habitat of the crab and leave it free to roam.
In the case of the marine pom pom crabs, the tank mates should include clownfish, gobies, blennies, and small species of snails. Lots of sea-safe fish do not bother with the crab and leave it to roam the reefs. Depending on the starfish, small shrimp, as well as hermit crabs, can be compatible. Remember to keep off aggressive fish such as triggers, puffer, or big wrasses since they can attack the crab or cause it to lose its anemones.
Selecting the appropriate tank mates will ensure peace of mind and lower stress levels for the crab. One must never put two species of different sizes, temperament, and water demand in the same environment.
