Electric Blue Hermit Crab

Electric Blue Hermit Crab

The Electric Blue Hermit Crab are most definitely one of the most vibrant crabs in the marine industry, and are usually one of the most sought after due to being relatively rare in comparison to others. It holds electric blue and black banded legs and bright orange antennae, as well as large and small green/brown claws. 

When housing this crab it is important to add additional shells to the aquarium, otherwise as it grows it may sought to attacking other crabs or snail in order to take their shell. It is important to note that this crab will also not tolerate any copper medications and it will mostly kill it.

Another reason as to why this crab is so highly sought after is that they are an amazing member of the clean up crew family and have a great ability of eating cyano and hair algae, which make them very appealing to hobbyists. Additionally, they provide a service that consistently aerates the sand bed as they scavenge through it, which can be invaluable in stopping nitrate built ups under the sand. Lastly, these crabs are reef safe and can live happily within reef aquariums with lots of corals.

This crab will most likely be content with eating the algae in your aquarium, but if there is an insufficient amount present then it is important to feed them. This can be done by offering a variety of herbivore preparations.

  1. These are pretty, and very active. The ones that I recently got from LiveAquaria all survived & immediately adapted. They keep trading off shells, which is fun. They have done much better than the Halloweens. I lost two of the Halloweens shortly after arrival. These little Electric Blue guys are fun.
