Oh I can't see the links, they're broken I think.
She really needs a heater then if there was possible Ich. Ich cannot survive (except for one strain) in high temperatures at 85-86 degree's so I'd suggest getting that 10 gallon back up as soon as you can to at least get her in warmer water, it's most likely the reason she's clamping right now.
To disinfect the 10 gallon, take all gravel and decoration out. Rinse gravel in very hot water and leave out in the sun to dry on a towel or something.
Get some white vinegar and rinse the 10 gallon with it, I use a paper towel to work it in. Then rinse out with extremely hot tap water multiple times until you no longer smell vinegar. Let dry and you're set to set it up again. Do the same with the heater and filter (not filter media) rinse with some vinegar and then hot tap water and let dry. You'll have to get new filter media which should be easy
Set it up with gravel and decor, let it run for at least 48 hours before putting her in to make sure that everything works again.
Do you have a liquid test kit to watch out for ammonia and all? Since you're starting over your tank won't have a cycle running so it will be easy for ammonia to get high and poison her.
