Our local Wal-Mart is now selling live crayfish. I was surprised
to see them in the tank at the store. How common is it to have
crayfish in one's aquarium?

One of the crayfish was dying. They've only been there for a couple
of days. I'm waiting to see if any survive.

(I have a zillion questions about them, but I'll google them!)


They are aggressive and will fight your fish for food, or even us your
fish as food if it can catch it. If you're going to keep it, keep it
with fish it can't catch and fish it won't be competing for food with.


They will also uproot plants and push gravel/sand all over. And don't
underestimate their agressivness. They are mean critters. I tossed 6
one inch crayfish in my 110 gal tank as food for my Rock Bass.
Apparently two escaped the wrath of the rock bass cause two months later
I saw a 3inch crayfish emerge and seize a 2 inch catfish! The *******
was impossible to net so I ended up fashioning a harpoon from a needle
and a 3 foot dowel rod. After an hour in a semidark room, I managed to
harpoon it. I was happy until a week later, another catfish
disappeared. Yep, there was a second crayfish, just as big. Harpooned
him too!
