Can Fiddler Crab Share a Tank With African Dwarf Frog?

Can African dwarf frog live with fiddler crab?

Having frogs, especially the African dwarf frog in a tank is so cool and nice, but have you ever thought about placing it with a tank mate?, I think that will be awesome. But the problem is, what can they live with. I have read several threads in many fish forums, where some individuals raise a topic about having fiddler crabs in the same tank with African dwarf frogs. This article is to educate you on the possibilities of these 2 creatures sharing a tank.

Can Fiddler crab and African dwarf frog live together? No, fiddler crab is a brackish water dweller, while African dwarf frog is a freshwater dweller. Also the fiddler crab might try to kill the frog if they share a tank.

It’s a proven fact that no frog could live in a brackish water, or can at least survive on such water for a long time.

On the other hand, fiddler crab, unlike other crabs is a salt water dweller and will not survive for long if placed in a freshwater.

So it’s a pure fact that there is no how these 2 creatures could be able to share a tank and survive.

Many people think they can make these 2 creatures to coexist by buying aquarium salt and putting it in a freshwater, in order to harbor the 2 animals in the same tank.

Well, trust me, that strategy won’t work because once you add salt into your aquarium, it will harm the frog who is very prone to salty water.

Again African dwarf frogs although are water animals, but they can not stay submerged for a very long time, or they will drown, so they need to surface once in a while, unlike the fiddler crabs.

Another reason why they cannot coexist is, if they do, there is every possibility that the crab will try to kill the frog or the frog will end up killing the crab.

Crabs are fond of going to the animals around then, in order to try to kill them and eat, so if kept together with an African dwarf frog, it will end up trying to kill the frog, and on the process might fatally wound the frog with it’s claws, or the frog might try to eat it, especially during it’s weakest moment when it molts.
