Thanks Sue! Like I said, I've never cycled a tank with only one fish. Ali hasn't shown any sign of ich at all...I'm just a worrywart I guess.
I love bettas! Funny...when I bought him the guy at the lfs followed me around telling me that bettas and goldfish are the only fish that don't need heaters or filters, lol.

Then he started talking trying to sell me something to help the tank cycle, and I told him I'd probably put some media from the gf tank in there to get it started. He immediately started lecturing me about how most people don't realize how filthy and nasty goldfish are and if I did that I'd kill my betta with ammonia!

I told him that I had 2 goldfish that I'd bought from them when they were 1 inch long and that now they were at least 7 inches, and thank you very much, but I know how to take care of my fish. He still followed me telling me that if I wanted to breed bettas, that the female would kill the male after she has the fry!!

I couldn't help it...I laughed and told him that made a female betta smarter than female humans!
He left me alone after that, lol.
