Thai Micro Crabs are one of the smallest species of crab in the world, and their small size is part of what makes them so fascinating to observe.

Keeping them with larger fish is not recommended, as they’re virtually defenseless and could easily be eaten. However, they can make great tank mates with other small aquatic species, such as Cherry Shrimp or Pygmy Corydoras.

Lifespan
These tiny creatures have a lifespan of around 1.5 years and require a stable environment with warm water and vegetation to forage in. While their lifespan may seem short, they compensate for it with their unique appearance and low-maintenance care.
Keeping their tank clean and maintaining a balanced pH level is important to ensure their full lifespan.
To extend their lifespan, you can also provide them with a varied diet that includes live or frozen food, such as mosquito larvae. Additionally, you should avoid housing them with larger fish that could eat them and make de plenty of hiding places and natural decor in their tank.

Appearance
If you’re fortunate enough to observe the Thai Micro Crab up close, you may be amazed that they are similar to their larger relatives. Their bodies consist of a round carapace and are usually a silver-gray hue. Their legs, however, may have a warmer shade of brown and appear slightly transparent.
These crabs have often been mislabeled as spider crabs. Their legs are abnormally long compared to the rest of their body, and they tuck their ten legs in close to their body.
Something unique about the Thai Micro Crab is the filaments growing from their legs and claws. They use these hairs to trap tiny food particles in the water, which helps them greatly during their scavenging for meals.
In terms of size, there is usually no distinction between males and females. However, it is relatively easy to identify the females due to their rounded bodies, and males generally have narrower and more pointed carapaces.
Celestial Thai Micro Crab Care
If you’re considering getting a Celestial Thai Micro Crab, it’s important to know that they require a small tank of at least 5 gallons and a slightly bigger one if they are kept with fish.
Thai Micro Crabs are very adaptable and undemanding regarding environmental conditions. However, they can be adversely affected by radical changes in the water quality.
You must maintain stable water quality with a neutral pH balance and warmer waters.
It is crucial to set up their tank with thick vegetation foraging and hiding places. Remember, like other freshwater crabs, they can suffer from bacterial and fungal infections.
Tank Size
Your tank size should be at least 5 gallons for the Thai Micro Crab and slightly larger if you plan to keep tank mates with them. These tiny creatures don’t require a lot of space, but they do need enough room to forage for food and hide when they feel threatened.
A larger tank also means more opportunities for natural decor and vegetation, which is important for their well-being.
Here are three reasons why you should consider a slightly larger tank for your Thai Micro Crabs:
- It allows more room for their tank mates to swim around without disturbing the crabs.

Water Parameters
Maintaining proper water parameters is crucial for the health and well-being of your beloved Thai Micro Crabs. These little creatures require a specific environment to thrive, and any deviation from their preferred conditions could lead to stress, illness, and even death.
Aim for a neutral pH balance between 6.5 and 8 and a temperature range of 75 to 82 degrees Fahrenheit to ensure your crabs are happy and healthy. The hardness of water can range from 6 to 15 dKH.
You can use a heater and a thermometer to monitor the water temperature and a pH test kit to measure the acidity levels. Remember that sudden changes in pH or temperature can harm your crabs, so it’s best to make any adjustments gradually.
In addition to pH and temperature, you should also pay attention to other water parameters, such as ammonia, nitrite, and nitrate levels. These compounds can build up over time and cause toxicity, leading to stress, illness, and death.
To prevent this, you should perform regular water changes and use a good filtration system that can remove any waste and debris from the water. You can also add beneficial bacteria supplements to help break down organic matter and maintain a healthy biological balance.
By closely monitoring your water parameters and ensuring they are within the optimal range, you can provide your Thai Micro Crabs with a safe and comfortable environment that will allow them to thrive for years to come.
