Alright thanks.You would absolutely need to seperate them. Tarantulas are extremely prone to cannibalism (except for a very few species, Grammostola rosea is NOT one of these). You will end up with one very well-fed tarantula if you attempt to keep multiple Grammostola rosea in one enclosure. The good news is, each tarantula needs only a small amount of space (3 to 4 times their legspan), so setting up a new enclosure for a second tarantula shouldn't be a problem. I would, however, recommend looking at other species - G. rosea tend to be pet rocks and can get boring. Adding new species to your collection will let you observe new behaviors.
Would you recommend another species? I don't want anything fast-moving or aggressive, but an active spider would be nice.
Woah! He's been making rounds in his enclosure, just going around and around the entire tank. What's this all about?! Maybe it's exercise hour? Could he be looking for the cricket I tossed in there yesterday (who is still chillin' in there with him)?
