I forgot to mention that most pet stores call the white crayfish a "vanilla lobster".. I see it all the time. That's why my hunch is such.RyRyTheAquariumGuy said:I think what this post is actually referring to is the freshwater white crayfish. They are a sister species to the blue, orange, red, etc.. However the white ones for some reason tend to be wayyyy bigger than the other colors. Probably around 5-6 inches fully grown in some cases.
I would say at least a 20 gallon LONG tank because they need the floor surface. You could probably get away with a 20 gallon HIGH but nothing smaller as they will go nuts and rip up everything.
In fact, they may rip up next to all plants that they can so be prepared. My blue crayfish was like 4 inches and ripped up my subulata like it was his job.
