The whole reason that I got my own betta fish is because my boss asked me to betta-sit for her over the summer. My boss has a VT male in a gallon vase along with some marbles and a plastic plant. When I got my betta, I obviously did a lot of research on here and got a filtered, heated tank (1.5 gallons. I know it's a bit small but I am looking into getting him a 5 gallon tank.)
I want to encourage my boss to purchase a tank for her betta (or, if I have to, I might try to at least give her my 1.5 gallon. I know that it's not ideal, but it HAS to be better than the vase.)
I'm afraid that she likes the vase because it "looks pretty."
I just need a bit of advice on how to talk to her about upgrading to a tank. She has had her fish for a lot longer than I have had mine. I know that this isn't her first fish, because she told me before she left that if he died, she wouldn't be getting another.
SO-how should I talk to her about getting a filtered, heated tank for her betta.
Also-besides frequent water changes, what can I personally do for her betta while she is away to make his life as good as possible? I don't want to put him in a tank just for him to go back into the vase at the end of summer.
Thanks in advance for all of your help :)
