Right now we have...
3x Latrodectus bishopi
1x Latrodectus hesperus
3x Sicarius sp slings (slings = babies)
5x some sort of trapdoor spider slings
1x OBT sling
1x unidentified Chile sp
1x Hogna sp (wolf spider!)
1x Acunthogonatus pissii (my favorite! I handle it a lot)
1x Chilobrachys andersoni
1x "blue fang" sling, I'm not certain of the Latin name.
3x Tegenaria sp
We also have two millipedes (C. gracilis) and two Florida Bark Scorpions who are very gravid and should pop any day. He doesn't have everyone labeled so I may have misspelled a few!
I'll use our widows as an example (all of the Latrodectus, his favorite genus). They have coconut fiber mixed with a little sand for substrate, they live in 16oz deli cups. Depending on the species, some get larger, some smaller, some deep, some wide. They're fed primarily crickets, once per week or so. Some sp get misted, some don't. Most get their water from their prey. They don't really produce a lot of waste, cleaning isn't really important. Obviously we do, but many people don't.
I need to get some of R's pictures up on here, he's been taking some really fabulous ones.
