Woohoo! I picked up a pair of blue FW
crayfish tonight. What a deal too. Buy one - get second one 1/2 price. I got two of these beauties for $34. All the other lfs
near me are selling blue crayfish for $30 - $40 each!
I've got them in a 10 gal
with a black gravel substrate and red lava rock. I've read that high temperatures shorten the lifespan and increases aggression, so there is no heater - the water is a constant 73oF. Crayfish like well oxygenated water, so I'm going to put in a bubble wand.
My only concern is aggression between the two crayfish, but I was told that this will not occur if they are well fed and have lots of hiding places. Here are some pics of the crayfish and their new home!
