I have a chinese fighting fish, and i dont know if its female or male, and theres a a pile of bubbles in the corner of the tank. I used to have a chinese fighting fish [F] and my brother had a male one. They both had seperate tanks, but still mine seemed to get pregnant. But this fish hasnt seen another fish in ages. Can you please tell me if this fish is gonna have babys or if its just bubbles?

ALSO the fish keeps swimming close to the bubbles, as if shes gaurding them, and she also took a bubble from the other side the tank and took it to the pile.
