Thank you every one for your comments. Jessie 7 doesn't look too good tonight. He was beautiful and flaring and swimming around when I first put him in the tank but tonight he is sitting on the bottom going up for air and then nose diving back to the bottom. He's not in the same tank as 6 was either. I took him out and put him back in his cup with a little bit of the water that is keeping Rusty doing so well and floated him in Rusty's tank to keep his temp constant. Both tanks are 82 degrees. Neither seemed to care that the other was there. Granted they did have plastic keeping them apart. Finally, they both flared up a little and Rusty jumped which scared me (not out of his tank just away from the flaring Jessie).
I checked the ph and it's high it both tanks i don't have the kit for the other parameters. Both tanks are half treated tap and half r/o water.
I'm concerned Jessie won't make it through the night. Of course I will promptly march him back down to petsmart if he doesn't but like I said he is my favorite of all the bettas we have had. Not to mention I don't want to lose any more of my babies.
