yeah, crayfish are awesome i had them aswell,i had a blue/white freshwater "lobster" if that's what it was, it was awesome,it too would beg for food,could'nt keep anything with it too aggresive it was big too,i think it was a cherax sp.I keep blue crayfish - amazing, responsive little guys. I love watching them eat. He practically begs for food when I'm near the tank. As I'm typing this, there is a crayfish on my shelf peering out from his cave at me
Blue Ring? Those are nasty little things. I would love to have one if I was ever to start a salt water set-up but since the time and cost that go with one are prohibitive for me I guess that it is one dream that will not be realized. That and since i have kids in the house I would not want something like that where they might get too close to it.I used to keep many aquatic inverts. Both fresh and marine. I have kept everything from octopi, nautilus, many different shrimps, crabs corals ect. zi was lucky enough to actually breed the blue ring octopus.
I have bred some really nice tropical freshwater crawfish. I actually love inverts more then fish.
