I am going to ignore all posts that have to do with the bowl size.
Ok, so Toby wants to mate....why? Because he saw Sushi? I thought Sushi was a boy!Does Toby know this?
And do I HAVE to mate Toby? If I don't, what will happen? Could I mate Sushi and Toby together, though I think they are both boys?
I have alot of questions...
No, it's just a natural behaviour that occures in all bettas, even females.
It is sometimes influenced by the presence of another betta (for males, it can be competition), (for females, it's trying to mate with her).
Toby knows Sushi is a boy. You most certainly don't have to mate Toby, it won't affect him any to be celibate for his entire life.
And no, if you put Toby and Sushi in the same bowl, they will fight and likely kill each other.
im stuck at work lol
