Yeah, it did. I don't see anything he would have rubbed against. I'm pretty sure he's biting though because Zafirah told me he did when I adopted him. He's just weird.
he did that with me too. His tail used to be almost halfmoon. But, now you can see he has chewed it down. You could try switching his food. I used to feed Betta Bites. But, switched my food to Omega One Betta Buffet Flakes and 2 of my males stopped chewing. One of them was tyco. So maybe try that
Yeh they should have it. If they don't you could order it like you said or i could ship you some. Im thinking of seeing if i can buy it in bulk. Its a painb in the butt to buy a new bottle every 3 weeks
