Can crayfish and aquarium snails live together in a tank?. This is a very popular question amongst pet lovers. We all know how intolerant, territorial and aggressive a crayfish can be, they do not tolerate and so does not have much suitable tank mates. So are snails suitable tank make for crayfish?.

The truth is, asking if crayfish could coexist with snail is like asking if a lion could live with a goat or dear, I hope you know what the results will be, so both creatures can never stay together in one aquarium.

Another reason why they will be very easy for crayfish to eat is, they are very very slow, infact crayfish is far more faster than snails. This will make them an easy prey for crayfish.

You might say that their shell will protect them from crayfish. The truth is, sometimes it does and sometimes it does not. If a snail is in it’s shell, a crayfish pinch can do absolutely nothing to him, but the snail must surely go about to look for food, etc, then the cray will get him, or even penetrate the shell.

They could coexist for sometime because snails are not that easy to be killed by a cray. They may choose to climb on the walls of the aquarium and stay there for a while or even climb anything they see in the aquarium, and when they are at the bottom of the water may decide to stay in it’s shell which crayfish can’t easily penetrate.

Apart from getting eaten, another thing to consider is, ‘ can their water parameters match? ‘. Even if the snails will survive the crayfish, the nature of the snails may not match with that of the crayfish, and this will bring confusion on how to make the two creatures be comfortable etc and might lead to one of them having problems because the environment is not suitable for it.


Although some people claim to have some species of snail in the same aquarium with crayfish, I won’t advise that.
