My cousin is 11 years old, so please bare with me as this is about her. Her parents don't speak english (she is adopted -long story) so I can't discuss these issues with them. I don't have all the information, as basically I got most of this off a phone message)
My cousin has a goldfish (used to be two, one died - no surprise) in a one gallon bowl (I know its too small, I keep telling her that but she won't listen). And she has two bettas, both in their own 1 gallon bowls, Marina and Samoa.
She wants to put her goldfish and one of her betta (i don't know which, the girl or the boy) together. She has an empty ten gallon tank.
I know nothing about goldfish. But from what I can gather, goldfish and bettas can't be together mainly because of their temperature needs. Is this correct? Are there other reasons for this, because my cousin won't listen to just one reason? Bettas are also fin nippers in general, so wouldn't they nip at the fins of the goldfish.
I think she is planning either:
-goldfish and betta together in 10 gallon
-goldfish and betta SORORITY
She isn't listening to my advice, please give me some backup on this.
Since I've gotten into the betta hobby she has decided to follow, not listening to all of my advice. Because I recently made a sorority, she has decided SHE wants one now. PLEASE HELP. I am afraid for these fish.
