Mini Chili Crabs are interesting additions to an aquarium, but they require certain attention and care. These tiny guys, though full of life and color, can trouble aquarists in terms of tank configuration, conditions in which the water should be maintained, and overall care.
Content Table
Prospective and first-time chili crab aquarists need to be informed of the fish’s needs so they can provide the appropriate care. In this article, we will learn all about these aquarium crabs including: what makes them unique, how to choose their habitat, and how to take mini chili crab care properly.

Aquarium Crabs
As for now, freshwater and saltwater aquarium crabs are popular for their performances and appearance in the aquarium. They are crabs belonging to the families Varunidae and Gecarcinidae in the larger order Decapoda. Gouramis are fish that feed on algae, leftovers, and other debris that must be cleared from the tank. Some are also noted for their habit of swimming in the bottom of the substrate, thus making any aquarium more interesting.
Common Species of Aquarium Crabs
- Red Claw Crab(Perisesarma bidens) – A semi-terrestrial species, commonly found in brackish water tanks.
- Fiddler Crab(mjoebergi) – Known for their distinctive asymmetrical claws, which are much larger on one side.
- Dwarf Crab(Cambarellus spp.) – Small freshwater crabs, ideal for nano aquariums.
- Cherry Shrimp(Neocaridina davidi) – While technically not crabs, they are often included in aquarium setups for similar roles.
- Blue Lobster(Cherax destructor) – Although a lobster, this species is sometimes kept in large aquariums for its striking blue color and interesting behaviors.
Mini Chili Crabs Live In Aquariums
Mini chili crabs, scientifically known as Ilyoplax deschampsi, have become increasingly popular among aquarium enthusiasts due to their small size, vibrant colors, and fascinating behavior. These tiny crustaceans, native to the coastal regions of East Asia, bring a unique charm to freshwater aquariums.
Peculiarities of Mini Chili Crabs in Aquariums
- Size: The adult size is about 2 inches (5 cm) meaning that they are perfect for nano or small shrimp aquariums.
- Habitat Needs: Mini Chili Crabs are more specific and like waters that have salty content, although they can dwell in freshwater, the water has to be spotless. They like tanks with adjacent shelters such as rocks, driftwood, or plants, which afford them protection.
- Diet: They are generalized, or operational, predators, which consume algae, detritus, and small invertebrates. While in captivity, they can be fed with algae wafers, shrimp pellets, and other blanched vegetables should be used.
- Temperament: They are relatively peaceful but can become territorial, especially males, which may show aggression towards each other. It’s best to keep them with other peaceful tankmates like small fish or snails.

Species and Growth
- Species: While commonly referred to as “mini chili crabs”, there are several closely related species within the Ilyoplax These species may exhibit slight variations in appearance and behavior.
- Growth: These crabs have a moderate growth rate. They typically reach adult size within a few months.
- Lifespan: With proper care, mini chili crabs can live for several years in captivity.
Mini Chili Crab Tank Set Up
The methods required to complete the mini chili crab tank setup consist of the creation of conditions as close to the natural environment of these crabs as possible, namely brackish water, retreats, and vertical space. Here’s a step-by-step guide to setting up a suitable tank for Mini Chili Crabs:
- Choose the Right Tank Size
- Tank Size: A 10-gallon tank is adequate for several Mini Chili Crabs in a small group. Larger water tanks provide stability for the water, but a small tank will do if it is well maintained.
- Shape: A long or rectangular one is preferred as it provides more surface area and space for climbing as required by Mini Chili Crabs.
- Prepare the Substrate
- Substrate: Fine smooth sand or fine gravel should be used. Crabs like burrowing and abrasive materials can hurt them and also their softer underparts. Sand is also another great medium that offers a natural habitat to the burrowing ahead of time, it’s important to have burrowing mediums ready for the Hills which includes, sand which is a good medium in the provision of natural burrows.
- Depth: Make sure that there is enough substrate to throw in the making of burrows at the bottom of the enclosure, which should be 2–3 inches thick.
- Provide Brackish water conditions regimes
Water Salinity: Mini Chili Crabs require either brackish or marine water with an accepted specific gravity of 1.010 to 1.020. The brackish conditions can be achieved by the addition of aquarium salt to dechlorinated tap water.

Water Parameters
- pH: A bit on the alkaline side, and preferably between level 7.5 and level 8.5.
- Temperature: Maintains the pH level of water at 7.2-7.6, and the water temperature at 75-80°F (24-27°C).
- Filtration: Sponge filters should be used and not the powerful ones which create currents to affect the crabs’ general health.
- Hiding and Climbing Places
Hiding Spots: Mini Chili Crabs require shelters where they can be found to avoid getting caught by their predators, especially when they are in the process of molting. Ensure that you have caves, rocks, pieces of driftwood, and aquarium ornaments that are of the hiding type.
Climbing Opportunities
Since they are semi-terrestrial, therefore climbing areas must be provided. Rocks, driftwood and aquatics plants should be placed in areas where the crabs can jump into the water and out of it.
- Land Area: A portion of the tank can have a land area or shallow water section where the mini crabs can rest and climb out of the water. You can create this area using rocks or a mesh platform.
- Add Plants and Decorations
- Live Plants: The beginner should consider introducing plants that are oxygenating such as java moss, Anubias, or Vallisneria into the environment. They also allow crabs to have places to hide and for the algae on such surfaces to feed on them and grow.
- Aquarium Decorations: These objects are important for climbing and for the hide. Some of the rocks, and tree truck decoration, are the driftwood among the aquarium-safe hardscapes. Make sure they are anchored down properly for they do not fall on the crabs.
- Ensure Proper Lighting
Lighting: It is not very stressful, but they require a fairly realistic light regime for about 8–10 hours per day. Marine LED light is excellent for plant growth and best mimics natural day and night patterns.
Red Claw Crab
- Fill the Tank with Water
- Dechlorinate the Water: the water used should be nonchlorinated particularly if it is sourced from the tap next to the tank.
- Test the Water: When the tank is ready add water and test the parameters such as salinity, pH level, water temperature,e and ammonia/nitrite/nitrate level that will help you to know that the water condition is appropriate for Mini Chili Crabs.
- Cycle the Tank
Cycling: Do not add crabs to the tank until the tank has been running for about 1–2 weeks. This will enable the friendly bacteria to form and balance the nitrogen cycle, which will reduce danger to your crabs.
- Add Tankmates (Optional)
- Tankmates: Mini Chili Crabs can live safely together with other friendly fish such as guppies, tetras or snails. Do not approach or disturb species that may prove aggressive and threaten the crabs.
- Avoid Large Fish: Avoid choosing fish that are of a size that will scare or eat your crabs.
- Add the Mini Chili Crabs
- Introduce Slowly: Before introducing the crabs, the water parameters must first be tested and adjusted if needed. Make sure there are many places for them to hide while they become familiar with the new place.
- Monitor Behavior: It is also important to monitor your crabs and ensure that they are not stressed, or attacking one another. Sometimes, it is required to change the tank or increase the number of shelter facilities.
