She clearly does not know what she's doing, or is very neglectful. The males will fight to the death when they get to a certain age and the females are semi-aggressive but still aggressive. Their dead bodies will pile the ammonia which will poison the fish intensely and kill them all. Try asking her to sell the remaining bettas to a local pet store. If she won't listen to solid facts, the fish would be better off in someone who knows more about what they're doing, and won't risk their lives out of fear for bad sales. If not, this may be a bit of a stretch but If I were you, I would offer to adopt as many as I can. Clearly if they stay in their environment they won't last very long. Does her tank look big? What are the levels (if she'll tell you)?
I don’t even thinks she even tests the water. She also doesn’t know the size of the tank. I think it’s around 15-20g. Not very sure as she just gestured to me the approximate size of the tank and I have never seen a tank larger than 7g. She did say that the tank has pondweed. I don’t think she can sell them as she is only 13 like me(don’t think her parents will approve). I will try to ask her to jar the males or sell them. I can’t adopt them as I can’t get more tanks(my parents don’t let me) and I don’t think she’ll give one to me even if I had tanks because we are not that good of friends.
I guess I just have to try to convince her. She has a tank of I think around 20g with 10-20 angles can’t remember what is the exact number but that is clearly overstocking.
