The Halloween Hermit Crab is a standout member of your aquarium cleanup crew, thanks to its striking orange and red banding. This crab's attractive color variation adds a beautiful accent to any marine aquarium. Beyond its aesthetic appeal, the Halloween Hermit Crab also plays a crucial role in maintaining a healthy aquarium environment. It helps clean up any leftover food on the substrate and efficiently eats algae, including green hair algae and cyanobacteria.
In addition, the Halloween Hermit Crab is known to aerate the aquarium substrate by sifting through the sand, making it an even more valuable asset. However, as it grows larger, it may accidentally disrupt rockwork or corals in reef aquariums, so it's important to be mindful of its size. It lives in abandoned snail or triton shells and may even attack and eat a snail to use its shell as a new home. To prevent this, make sure to provide the Halloween Hermit Crab with empty shells of varying shapes and sizes.
If there isn't enough algae present in the aquarium, the Halloween Hermit Crab will need to be fed dried seaweed as well as meaty items like mysis shrimp.
