My 2 year old son has a male Betta that we got him last year. Yesterday we were at the pet store and he wanted another Betta. I asked 4 different people who worked there to see if I could put a female Betta in with my male. Every single person said that it would be fine. So we got the fish.
We brought her home and put her into the tank with the male. They seemed to be doing fine but some hours later I noticed she was laying at the bottom. She wasn't moving but she was breathing. As I stood there watching the fish for a minute I noticed that the male kept charging at her. I then took her out and put her back into the little bowl she came with.
So really my question is....
Do male and female Betta's often fight? Is this part of their mating? Or could he be extra aggressive because he's shared a tank all to himself for a year.
If they can live together then I plan on going to get a 15-20 gallon tank this weekend. If not then I'll just buy separate little tanks for each of them.
Advice is much appreciated.
