Bottle questions: Hot water soak to scrub off the label. It does come off pretty easily. Then, just a utility knife, and friction fit.
I puncture some holes in the bottom to help it sink.
Your serpent stars will come in after the bait, so don't bait it.
I have better luck getting the crabs the way that Chesapeake crabbers do it--a bit of bait to get the crab out, and scoop it up with a net!
I still have 1 mantis that I'd like to remove, but it isn't killing anything noticeable (besides pods) right now.
Water to be removed: I put no shipping water in the tank (except for what was clinging to sand & rock). If you leave a few inches at the top of your tank, you'd be amazed as to how little water is displaced per pound--Each 8 lbs of rock (or sand) displaces about 1 gallon of water. So, if you are receiving 55 lbs of rock and 55 lbs of sand, that's about 12 gallons. I left about 4" unfilled at the top of my tank, and topped off after putting in the package.
Now remember, all you guys (and gals): We want to see photos!
