From my own T's it would be:

1. Pamphobeteus sp. 2Equador (Regularly leaps half way up the tongs :blink: )
2. Haplopelma Lividum (she is just plain NASTY!)
3. Lasiodora Fracta (she is permanently mislik ...)
4. Heteroscodra Maculata gal - need i say more ... :dry:
5. Hapalopus Formosus - Cutest aggresive lil T :lol: at 0.7mm already flicking hair and doing threat poses!!!

My H Minax and S Calceatum are relatively laid back ...

Hennie, I agree. My female B.Vagans is very ill tempered. During the last transfer, she immediately reared up, venom dripping from her fangs and bit my tongs repeatedly.

After 10 strikes she gave up the fight and allowed me to move her.

She is even worse during pre-molt stages. . .

In general I would say the old world species are more prone to bite. But never underestimate any tarantula...even the most docile and calm tarantulas can bite...And their bites might be worse since it will be completely unexpected.

Without a doubt, my demon infested, ninja trained, jump biting #$@! $ N.chromatus.
Apart from psycho, I must say most of mine are fairly chilled.
My L.klugi is a bit skittish, but nothing too serious.
Still need to get some old world species. .

Sent from my GT-N7100 a long time ago and far, far away.....

I would agree with both the B.vagans and N.chromatus, of mine those two are the most curious and the first to fearlessly come running towards any movement. I'm curious to see what my Pelinobius muticus will be like when it's grown some. At only 2cm it has real attitude already and just seems more hairy and robust than anything else.

Most of them are just defensive and not aggressive.. threat posing is still okay, but our calceatum just attacks. water droplets even she will strike at...and then ive seem some angry obts... for some reason our lividums have never shown any aggression.

Don't really receive any aggression from most of my spiders , but p.cancerides is pretty bad
