hey thanks alot for the info and i found that site and it says mantis shrimp can remember previous encuonters....
"A wandering stomatopod once came across a large tubular structure. Long, delicate-looking tentacles sprouted from one end to wave to and fro in the gentle current, and the arthropod moved closer in order to get a better look at the strange creature. In doing so, it brushed carelessly against the anemone, then jerked suddenly back in pain as the latter's tentacular appendages started discharging nematocysts. Stung by the unwelcome reception, the mantis backed off and hastily departed in search of its normal prey.
A few days later, it came upon the same anemone. Warily eyeing the cnidarian, it circled quickly around the large obstruction, and spared not one backward glance as it hurried along its way."
how crazy is that... anyhow these animals seem awesome...think i could keep anything else with it? not fish of course but maybe an anonome(for decore) or do you think thats a bad idea...
and yeah im going to make sure it cycles good before i do anything
**could you link me to the tank yuo bought....
and how deep is its sand?
could i possibly add a mate in later?
