The blue fiddler crab is a rare species that is barely seen in the hobby. Its scientific name is Uca Flammula but it is often referred to as the blue fiddler crab. The blue fiddler crab comes from the Ocypodidae family. Their maximum size is 2” and they can live up to 20 years. Fiddler crabs are omnivores that will scavenge leftover food from the tank. Blue fiddler crabs have a minimum tank size of 5 gallons. Fiddler crabs are considered semi-aggressive and should be kept in a species-specific tank. Fiddler crabs have been known to be aggressive towards small fish. They are considered coral and invertebrate safe. Fiddler crabs are special in the fact that they require air, this means that the tank should be designed in a way for them to have places to go underwater but also on land. This can be done in multiple ways, one way is to have large tall rocks in the middle of the tank partway out the water, this way the crab can come out of the water but will not be able to get out of the tank.
