Hmm....I think if she was secretly upset she would have gone all out with her fish. Maybe not to the point of having 10 gallons for one betta fish, but maybe 3 or 5 gallons. I hope she reads the constructive comments. Not only can that tank fall off the wall, but it's almost impossible to heat. Even if she does do the necessary water changes to make up for not having a filter, there is no way that the water temp is completely stable. T_T
Not that I want to bash a 14 year old for not taking perfect care of her fish. I thought using a filter in a 1 gallon meant I only needed to change the water once a month. In hindsight, I think I got the care directions for 1 gallon tanks mixed up with the care directions for 10 gallon tanks. I still don't know how my first betta survived. XD
She just needs gentle correction. I may leave a comment later. :)
