This undemanding dwarf crayfish makes a good tankmate in community and planted aquariums. Its small size makes it a safe addition to most set ups but should not be housed with large fish or large crayfish which can possibly mistake it as food. The blue mini mexican crayfish will happily eat leftovers but supplementing with algae based diet, vegetables, and frozen food will provide it the nutrition it needs to thrive.
