Aww, bummer. And don't worry, I'm not holding anything in, but it is a wierd story.
I went into Petco with my mom and brothers to get some toys for my dog about a year ago. I wanted to look at the Bettas, because I had $30 and I loved having them when I was younger. So, I saw a little Halfmoon that I loved immediately. I got a half gallon tank kit and the fish and spent all of my money. For easter I got a 1.5 gallon filtered tank, but Ink (my halfmoon) died of Ich a few weeks after I put him in. I didn't know it was Ich, though. So, I just cleaned the tank, rinsing it out and putting in a new filter cartridge. Then I got 3 guppies. They died of Ich after 3 weeks. I was really sad now, but I wasn't giving up. I got a little Betta named Rainbow, a dark blue/silver betta. He got Ich, but this time I knew about it. I went to Petco and the lady there reccomended Bettafix. Well, that did nothing to help the Ich. It healed a tear, but I could have cared less. He died 2 days after July 4th. But, I cleaned out an old fridge in the garage, and my mom said as a reward I could get a new betta. That fridge was sparkling when I finished. I got a crowntail and a new tank! And I still have him. I bought some Ich preventative and treatment, because I never wanted to deal with that awful disease again. Since then I have gotten 2 more new bettas from Petco, and they are all flourishing. You can't give up! The end. Told you it was wierd. :P
