Narrative: This is probably one of the hardiest crayfish as it can tolerate a wide range of water conditions, including low brackish environments and temperatures. It is an interesting crayfish to start with and comes mostly in red coloration but occasional variety of colors such as blue and white make it to LFS.They are aggressive and will attack most other tank mates.
