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!
