It's awesome to have family members that are as obsessed about this hobby as you are! My father has been in the hobby since the Early 80s and to this day still has a few tanks.
My mom also has a 10 gal fowlr. My dad jokes about getting a 300 gal lol. He really wants a decent sized tank so he can get a big lion. I wouldn't be suprised if he flew me down to set one up for him!
