Blue crayfish question

I want to set up a 10 gallon blue crayfish tank. How many can comfortably live in a 10 gallon tank? Also, how long do they typically live?

If you're talking about electric blue crays, a 10gal is too small for 1. I would go 20gal per cray and even then you may get fights. They need lots of hiding spots/caves, they will eat any plants in your tank, try and eat fish, snails, shrimp. They will get up to 4-6 inches in size.

20g platy, , 2 x 10g shrimp, 3 x 20g shrimp, 7.5g shrimp and 1 great dane/mastiff puppy.

Yeah a 10 gallon tank will be too small for it eventually, I bought mine at about 1.5 inches back in the beginning of August and it has molted about 4-5 times since then, and is almost 4 inches long now. A 20 gallon will be fine for 1 at most.

Yeah, I was thinking the same thing. I really do not want to dedicate a 20 to one crayfish. It's not that I do not like species tanks, it's just the fact that I think it may become boring. I have a pair of drarf cajun crays that I seldom see. The thought of adding some shrimp crossed my mind but I abandoned the idea after watching a cray at the LFS repeatedly try to snag a Danio in the same tank.
