I have a male beta fish in a large tank with filters and a temp of about 82. I also have in two cory catfish along with him. What other fish go well with them?
I do not really recommend having any fish with a male betta. They tend to fight because they are very territorial. I would not put any more in or you might end up having fishies floating in the morning like I did.
I would be very careful because hes a male but I know Neon Tetras go well with betta's. I would recommend getting a larger amount of Cory's because they look good and they are more interesting when in larger amounts such as 10. You can also put snails. They are cool but can take over your tank!
