A Uniquely Colorful Spider

Personally I find that my Green-Bottle Blue is a lot harder to care for than my Red-Knee (which is a beginner spider) mine wasn't eating for a long time (over a year) which I heard is normal but he still hasn't gained much of his weight or color back or spun any new web tents. I figured he would over time but i guess in his "weakened state" and the winter was too much on him . Anyways onto topic, for you more experienced spider collectors i guess, the Green-Bottle Blue is a very uniquely colorful spider, but like a rose, and yes the cliché, it’s got its thorns  they have some bad temperament issues in a way not so much as aggressive but they are so skittish and quick to defend themselves. My Red-Knee a very docile species takes a lot of poking and prodding before he kicks hairs but my Green-Bottle Blue (and I’m sure this goes for all Green-Bottles) immediately raises to an aggressive striking position when bothered or darts somewhere so fast you literally can barely see it move . The Green-Bottle Blue is definitely by all means a "display pet" probably owned by experienced collectors.
If you do end up wanting one though, you need the basic supplies any spider would need, a bedding of dirt (for best measures and safety I have organic potting soil) a heating pad, a shelter (broken pots, work well) and since it is semi-arboreal  I’ve added some branches (but be careful the last thing you want is to grab some foliage with pesticides on it, its better to not grab branches from outside in the first place I believe, but if you must be careful). Last of all they eat the normal diet of crickets and drink water (in a shallow dish).

hi...i agree with most of what uv stated about GBBs. yes, they are more of a display spider and not so much a T the average keeper wants to handle. not quite sure why u had a problem with its growth rate? every GBB iv had has grown from 1/2" sling to 5" adult in less than 2 years...?
also, and please dont take this wrong, DO NOT USE HEAT PADS!!!!  that may very well be the reason ur GBB died   =(
tarantulas heat sensor organs are located on there upper side(on there thorax). by placing a heat pad under the tank, the tarantula will, naturally, be attracted to the hot side of the tank. a heat pad can reach temperatures above 110 degrees+  and being that there sensory organs are on top, they wont feel themselves literally cooking from underneath.
 im sorry for your loss

yes i am aware about heating pads but that is why i found a very weak one and had anuf dirt the heated area that it only made a warm spot that was like 2x2 inches and the spider never spent much time on that side of the tank anyway, not in his shelter either  usually just out in the open...it was sad seeing him just waste away i tried all kinds of food he'd either try and fail or just run away from everything, and when he actually grabbed a cricket for once he died about a week after, as of now i'm good with my redknee, who is fat and growing

was it a male?...u refer to it as he, just wondering if it was a mature male and maybe thats y it died?
--im just stating this for readers--heat pads arent safe. if the temperature isnt right in ur T tank then u either need to raise the ambient temp in the room or use a heat emitter. i personally keep my T room around 78-82 degrees, so no external heat source is needed

yes mine was def a male it had its pedipalps or w/e they are called (i thot at first he had hurt his legs b4 i knew wat they actually were) and thats wat i was under the impression of  that maybe he was like ready to mate but didnt have a mate? or sumthing strange thing is tho that he was only bout 2 or 3 inches sprawled out and i thot they get alot bigger, i got him b4 he had his pedipalps as a juvi and only had him bout 2 years? as as for the info with heat pads to readers yes DO BE CAREFUL i have heat pads for other pets (that do need em) but u do have to be aware of how ur animal is gonna be with it, i have to watch my lizards cuz he'll move the sand and he could burn himself which is why i have a big rock over it so its like a heated warm rock more than burning glass

yeah...i used heat pads for snakes and lizards for years, but suggest against it cuz, like u said, they can just move the sand or substrate away and be laying directly on the pad(which temps can exceed 150degrees). heat emitters are the best, no doubt. heat lights work fine with reptiles, but Ts dont really like light too much...usually room temp for any T is fine-68-75degrees, unless, like me, ur breeding   =)
most Ts only live about 6 months to a year after they molt into a mature male(depending on species). sounds like there wasnt anything u could do, his time was up. 3-4" would be about right for the males of GBB, the females dont get much bigger than 5-6"
H.maculata males only live about 3-6 months after they mature and rarely eat- they have only 1 goal, mate and be the mates meal   =)

Thanks - a great review. Incredible that they can go a year without eating. How their metabolism allows for that long without nutrition is mind-boggling! Interesting to hear that they are definitely a display spider. I suppose their amazing color makes them worth keeping just for that reason alone.

yea i heard him making alot of noise moving around one day then saw he had a cricket and im like OMG! your eating lol xD itd be so long i didnt know if he'd ever eat again, hes been eating occasionally now, but i think he has some trouble grabbing the crickets? and he totally ignores mealworms of all sizes, i'm happy to know he's eating again but wish hed be a glutton like my redknee and be all big xD
