Their max size is around 1". Their care is very similar to the Cambarellus patzcuarensisand they seem to be very hardy as well. I keep them in ph of around
7.0 - 7.4 with a temp of 70 -76F. They share their tank of mine with some shrimp,
Snails and plants without any problems at all so far. These are very rare and not offered very often.
Please note these will usually arrive a light blue and in our experiance get darker as they mature and ready to breed.
