Well, this isn't exactly about bettas, but it kinda is.
I was talking to my cousin the other day (on the phone) Yes, the same cousin that has a Frog o sphere. :(
She had two feeder goldfish in a two gallon tank, and she cleaned the tank once a month. She kinda hesitated when I asked her how often she cleaned so I'm assuming it's not even that often.
Well, obviously, her goldies died. I told her she shouldn't get more goldies.. but I don't think she'll listen to me. Then I told her she should put her frogs in the two gallon in stead of getting anything else for it. Then she was like... I should get a BETTA!!!! I told her that bettas need really really clean water and a heater too, so if she wanted to do that, she should get a betta. But her mom won't let her get a heater.
Gah! Either way, some little fish is going to suffer! If she get's a goldie, it will die! If she get's a betta, it will die too, because it'll be too cold.
Sorry, just had to vent!
