Oh goodie, no problem. Those mean Pet Store peeps are the reason we're here now. I'm glad you are going to provide them with proper homes. Your Betta should live 4-6 years and your Goldies and live 20+ years.
Good luck! And remember to do water changes, and also get some liquid test kits so you know when the ammonia and stuff is getting too high for safety.
Oh Egypt? Cool!
