Well it's weird with my family.
My dad helps me setup my tank(s), he sighs everytime he sees me on the computer looking at "fishes" stuff, he likes the fish i get, but he gets angry when the tank starts to smell when it cycles, but i always tell him after the cycle it will never smell.
My mom has gone to numerous pet shops several times just for me, she always listens to what i have to say about fish and she likes the fish i get. The problem is, i buried myself under a 55g when i probably could've gotten a 75 or even 90g. They say no more big tanks, i will stick the smaller tanks under the 55g, and maybe a 30g in my room, or another 55g in my room.
My Oldest sister always buys my gifts ( bday etc ) fish related, which greatly pleases me, she always listens to what i have to say about fish, but she hates it when i feed live fish
My second oldest sister hates fish, but one night she asked my several questions about fish and she was actually interested, she doesn't like any of the fish i invest my entire allowance in but she likes clownfish, maybe a potential bday present??
My youngest sister sometimes listens to my rambling about fish, sometimes watches videos or looks at the pictures but other times she says she hates fish, until i tell her she can't name any, she always names them ariel
All in all, my parents are afraid of big tanks hogging space, we are 5-6 people in a 1,800sqft house and just downsized from a 3300sqft house, so things are mildly tough.
It just occurred to me while writing this, they would probably allow tanks of the same or smaller size of my 55g, that means i can stash 10/20/30g away in my room!
All in all, my family dont care about fish, except my only grand father who bred angelfish and kept clownfish and other various fish when he lived in cuba. He always listens to my ramblings about fish
