HAHAHAHA I would just grab the first thing you can get your hands on.
hi, Arachnokid 93! i'm locke. now i have 2 haitian giant centipede juveniles. one is 10 and the other is 9.5cm(1"=2.54cm). i only have experiences of keeping two species. Scolorpendra sp. "Haiti" and S. subspinipes dehaani "mau chau", vietnamese giant yellow leg. of course i'm not an expert of the pedes. but i'm telling you an advice of mine. the most important thing is to know each other between you and your pede first. you must watch learn many things about pedes such as their customs. so it's better if a baby individual then subadult or anything else. if he bites you, not much pain because it's small. and a small individual is easy to handle more than a big one. i don't care what species it is. most giant centipedes are similar to each other for custom, how aggressive, sensitive or anything else. many people say a giant pede is very aggressive. but i don't think so. of course they are enoughly aggressive in mother nature. but i think they could be accustomed to human's environment. it doesn't mean that they could be familiar like cats and dogs as a human's pet. but it could be possible if you enoughly try to treat them safe. watch this video below;
