Yeah, but this isn't the wild. It's captivity. You can't leave crickets in with the tarantula...So you must place one at a time in there. If he doesn't find it then the cricket could later eat him if he molts or crawl out of sight, die and rott and attract phorid flies...Also with a terrestrial species you're gonna wanna fill up the tank up with dirt halfway or more so the Tarantula doesn't fall and hurt itself. Why you ask? There's trees in the wild that it could climb and fall and hurt itself? Well...This isn't the wild. We do things differently to protect the tarantula. This is basic stuff. You should research. Besides...large tanks are more work when you wanna clean them out and they make it harder to locate a Tarantula. Tarantula's don't wander...It's a waste of a tank.Iam confused. Don't tarantulas in the wild live in large spaces? I just wanted to provide a large space for the animal Iam keeping. Not only would that be good for it but also it would provide enough room to make a nice looking set up.
