I am happy to see the tarantula fever is infecting some members . I contribute to this forum with a small species, Holothele incei. It can be considered a dwarf tarantula, females only reach 6 cm in legspan. They are heavy webbers.
But the interesting thing is the communal behaviour of this species, unlike most tarantulas these spiders can be kept together in colonies. I've read of people keeping them together over multiple generations.
I bought some slings with the idea to set up a communal tank, but then I decided to raise them individually, reproduce them, and start a communal tank from a single eggsac.
Here's my slings eating micro mealworms, they are just L1/L2.
