H. lividum is a fast moving aggressive species, it is recommended for experienced tarantula keepers only as it will take up a threat posture, and start striking out at the slightest provocation. As a burrowing terrestrial species deep substrate should be provided as it will dig it's own burrow and web the burrow and substrate surface heavilly. we feed ours on medium to large crickets, 2 or 3 once or twice a week, I do not provide a water dish for Haplopelma as the high humidity is more than sufficiant. Spiderlings are large 15mm legspan approx, and will grow quickly if well fed I have successfully bred this species several times, I have had more success breeding smaller specimens with a 3 to 4" legsapn, and very little success with the larger 5" + legspan specimens, suggesting they are sexually mature long before they are fully grown. Eggsac production can be anywhere from just a few weeks to many months after mating. Eggascs are usually small (perhaps due to breeding smaller specimens) a spherical sac carried, held by and rarely left by the female, an average number of spiderslings from H.lividum sac is between 40 and 80 (in my experience) perhaps more with larger specimens. Egg development at 85F is Nymph 1 (eggs with legs) at approx 21 days, moulting into Nymph 2 at approx 28 to 32 days moulting into spiderlings at around 45 days after the sac was produced.
