Crimped Fins, Scratching

[Stumpjumper]

I have a molly in my 20g, we have had him for a little over a week. I didn't want him, my wife did so I didn't pay a whle lot of attention to it. I noticed about 4 days ago that the fish's last two sets of anal fins are all crimped up and he is scratching on the deco a lot.

I have noticed no signs of ich on any of the other fish in there and there is no spots on the mollie either.

His condition is unchanged since I noticed. He eats when it's feeding time but he is usually either laying around on the bottom, or floating up on the top or scratching.

I have tetras in the tank and I am reluctant to treat for ich without any other visible evidence, I'm not really sure what to do.

My best guess would be Ich. If you wait for visible evidence you may lose all your fish. Ich is highly contagious.

If it's ich, raise the temp to 84 and add some aquarium salt, unless you have scaleless fish in there. They don't do too well with salt. If raising the temp doesn't help, you can treat with an ich med. I try not to add any chemical to my tank unless absolutely necessarily.
