One of these two is super fast! It is so fast, in fact, that I always put it into the fridge for a couple of minutes before opening his cage to feed, water, or clean. The cold will slow the spider down. The super fast one has never dug more than a small crater, but did molt a couple of weeks. So I've been waiting for #2 to molt. This one has been looking super fat and shiny, just on the verge of molting!
Just like with SFB, there was a cricket in the cage during molting. This tarantula, however, rarely emerges from his burrow. It was no problem to remove the small cricket.
I haven't seen this Brazilian Fire Red Tarantula out of his burrow since he molted. In fact, even when "he" does come out, moving or touching the cage at all has him racing back down into hiding! So I'm not likely to get a good photo of him for quite some time.
I don't know what I'll do when he outgrows his cage because, I fear, he will never stay out of his burrow long enough to be transferred. This behavior could change as he grows, though. SFB built a burrow just for molting. It has since collapsed. Then he just built a web hammock for molting this last time. I had even added more substrate for more burrowing.
I need to decide on names for the Brazilian Fire Reds and some of the others (suggestions welcome). I'm not sure if I'm ready to name the really tiny ones, though Elmo did name his Brazilian White Knee... Tiny.
