Help! Two sick betta's!

[Synthisis]

Did a water change in both Koi and Pineapple's tank last night.

Woke up this morning to find both fish laying on the bottom of their tanks twitchings.

Koi swims at a 45degree angle
Pineapple swims on his side, got pinapple in his cup but he swam out and jsut spiraled to the bottom of his tank and then landed upside down.

They are both in their tanks, water parameters are fine. Temps between 78-82.

Well I gave them both a warm salt bath and then switched them over to their cups and put them in about 90% bottled spring water.

So far pineapple is still on his side, lots of gill movement the whole time. Koi is either on his side, or point strait up to get air.

...Did you forget conditioner? Thats the only thing that comes to mind :/ I'm sorry I can't be of more help, I'm going through somewhat of a smiler issue with my fry.....

[Synthisis]

I always condition my water for 30minutes-1hour before mixing it into the tank.

Koi is looking better... hes jsut swimming normally in his cup right now.

Pineapple is moving his fins more and looking more alert, but is still on his side, or lays against the side of his cup.

[DragonFish]

Do you just let it's sit...? Or use actal conditioner too?
Eiter way, thats bizzar that it's just suddenly happening....maybe your water company added something new to their water...?

Good to know they're a little better....hopefully they both recover!

Sure sounds like a water issue to me.
I would keep them in the cups if they are improving, and do a 100 % water change.

Salt too, but I think you said u did that.

He always uses actual conditioner. I think he uses Prime like me. It's just strange because they were fine last night, swimming like normal.

Well they are still in their cups and my parents are keeping an eye on them while Im out of town. Apparnetly they are doing fine now. Koi isnt as active as usual... I think its ok there, and Pineapple is swimming around. Guess Ill see tomorrow.

[dramaqueen]

I'm glad they're doing better.

[Synthisis]

Well I came home and both fish flared at me in their cups... so Im not sure wth happened lol...

Im unhappy though, I dont know what caused it, how to prevent it, or if it will happen again.
