My Chile is docile in the extreme.
The only time I ever had a near miss was when I was about 16 and went away for the weekend - a piece of tape used to hold the thermometer in the tank had dropped off with humidity and fallen on the floor of the tank.
Of course as humidity in the tank fell over the weekend the tape regained it's stickiness and the spider got herself badly stuck - 3 legs on one side were trapped.
It took a very stressful hour with a pair of forceps and sharp scissors to cut her free, leaving each leg with a tiny tab of sellotape behind. About half way through the spider lost it and lunged for me three or four times. We got her free in the end though. Moral of the story? Don't put anything sticky in the tank...
Otherwise the only time I won't handle her is if she's not been fed - she spends the majority of her time sitting just outside her bark lair, although as a juvenile she was a prolific climber.
Sik:
That's the same species I have - sometimes they are much much pinker in real life. Mine almost looks orange in some lights. They are ideal beginners pets and cheap to buy too.
Remove dead food with a pair of long forceps, or your fingers.
Keep the crickets next to the tank (they like it reasonably warm)
You can't freeze them! You buy them live, and feed them to the spider live.
HEat mats should be about 1/2 the size of the tank. This way the spider has a choice of sitting on the "warm bit" or the "cold bit" of the floor - I think they cost about £15 from pet/reptile stores.
