Alright, I thought I would share what my mom told me, and showed me while visiting her house.
Well, she has a very gorgeous crown tail male betta in a 2 gallon tank.
She decided to see if he would be okay housed with two female guppies. All was fine for about two weeks when he began savagly attacking the female guppies. They were quickly removed.
About a month later, mom took a good look into the bettas tank, and low and behold he was gaurding baby guppies!
The strange thing is mom used to feed him guppy fry when she had too many, but he was GAURDING these ones. They were HIS babys.
She waited and waited, and expected them to be eaten, but every day there would always be his four baby guppies swimming around in there. He even plays with them. Its quite adorable.
Ive never heard of this, but it definitly tells you that some bettas can be real softies.
Ill have to try to get pictures next time I go up if mom didnt transfer them into her other tanks. Its quite a site.
(PS, the momma guppies are perfectly fine, just had some torn fins and missing scales).
