"But the fish store guy SAID it was okay!"
(bit of a word wall; there's a tl;dr at the bottom if you don't want to read a painfully long ramble about my childhood issues)
Hopefully I'm putting this in the right section...my particular case doesn't/won't involve betta fish, but I figure it must be a common problem, so I threw it up here to see what everyone else has to say. Fair warning, I'm typing this at 4AM with new-tank-induced insomnia (I dreamed that ALL the plants came to life LSoH-style and threw Altair out of the water, at me and there might have been a musical number, I don't even know. I might also have a fever. I'm sorry in advance.)
So, goodnews/badnews time. Good news, my newfound fish mania has potentially prompted my parents to get some fish of their own.
I live at home because hey, free food and no rent, and have overheard their plans to maybe dig a 'koi' (goldfish, they don't know the difference...honestly neither do I...) pond in the back yard (it's a 1-acre lot, we have the room if you have enough time/explosives to get through the lovely texas bedrock.) which is cool, we've had one before in a rental house. The fish surived even.
here's the bad news.
My parents have this problem where everyone on earth is more credible than I am. I have been told, to my face because my family does not do the shy thing, that I don't know anything about anything, over issues that I have been more qualified to deal with for YEARS. (computers mostly, but cats as well, television, luggage location, how to navigate new york city...)
Luckily they haven't physically tried to stop me from buying what my fish needs (Though I do get the 'girl you crazy' look from my mom at least three times a day.) but I've been getting "but the girl at the fish store said your fish is in a little fishie mansion, why are you upgrading the tank? (1.5gal->5gal)" Throughout this whole endeavor.
These are the same people who bought me a 10 gallon fish tank when I was five, stocked it with goldfish, platys and neon tetras, set it up in my room and changed the water when it was too murky green to see the fish.
and then restocked the fish when they died without ever changing their cleaning habits.
Because the fish store people said it only needed cleaning twice a year.
I love my parents, but really?
They're getting on in years(not gonna say how much to avoid offending anyone here) and turning even more stubborn as they go. The internet is not a credible resource, and neither are books because the fish store person said so. Unless what the fish store person says is inconvenient, in which case, it's because Dad's research says so.
I'm pretty sure I could drag a nobel prizewinning marine biologist in front of them with proof and it would still be because the fish store person said so.
I know that people have to have the problem, with Bettas especially, considering all of the urban legends out there about them.
tl;dr: My family is potentially insane and doesn't listen to me about fish care.
So, what do you do to avoid fish abuse when your family decides fish, bettas especialy, are a maintenance-free pet?
