tarantulas are solitary animals as well. You can keep them in large critter keepers but once again they prefer big cages. Long shallow ones with a lid lol. The like sand bedding and the bark like bedding (forgetting what it actually is) and the mossy kind (think wild natural habitat). Crickets and insects for food and a very shallow water dish. Fresh water every day and make sure its not too deep. They go into the dish to drink and it needs to be shallow. Once a month go through the tank and clean it; sweeping up old webs, dead crickets etc etc. You can add decorations for them to crawl on and a hidey hole.
I've personally never had a tarantula but I kept a wolf spider for 8 months before she laid eggs and died. My ex's father had 2 really big ones though. Pretty things!
If any of it is wrong please correct me, I'd hate to be giving the wrong info!
Feel free to message me any questions, I'll try to help the best I can!
