Ugh. What a mish mash of advice you've received to such a basic question. Can you tell us what other fish are in your tank, goldfishgirl? If the gourami is 'covered' in white spots, as you say, it sounds like it's somewhat advanced already. They usually just appear as a few spots on the pectoral or caudal fins, first. I would indeed crank up the heat in your tank to about 84 degrees, but you have to do it slowly... one degree every couple of hours is usually alright. Depending on what other fish you have in your tank, I'd also add aquarium salt - at least 1 tbspn per 5 gallons... if you've got tolerant fish, I'd go 1 tsp per gallon. If the parasite is as advanced as I'm suspecting from your description, you will indeed need some meds from the lfs, but again, what kind depends a lot on what other fish are in your tank. With the higher temps and chemical meds in the tank, oxygen will be depleted - increase the aeration in your tank and do daily 10% water changes, topping up the salt and meds to replace what was lost in the w/c. If you use carbon in your filter or filter cartridge, make sure to remove it before adding the meds or they will be filtered out. Good luck and please get back to us with an update.
PLEASE HELP! He was my first fish, and I don't want him to die... I just fed them and I noticed that my Kisser has a ton of white spots on his body and fins. I figured it was ick, so I would like to know what I can do to cure him right now.... Should I separate him from the rest of the group? If it truly is ick, how should I treat it? 
She has given you good advice. 
). As far as ich medications go, I've not had to treat a lot of ich in my time, but have been satisfied with the results of a malachite green/quinine HCL anti protozoan formula. If you read the active ingredients on the labels of all the ich/white spot meds in your lfs, you should be able to find one that contains these ingredients.
