White Spot?

[Woko1985]

My male betta fish has white spots on him I've had him less than a week,I've turned up the heat to 80f an I've had him less than a week what else can do

Get yourself a medication; I would recommend Esha Exit.
 
Your fish has probably caught the whitespot due to stress from poor water quality, so you'll need some test kits for ammonia and nitrite and be prepared for a lot of water changes until your filter is 'cycled' (ie, has a colony of good bacteria living in it to 'eat' the fish's wastes).

Thanks alot also 2 of my danios have there mouths wide open an have been like that for a day now the other is fine tho

I know I'm (dangerously!) assuming here, but I'm guessing this is a new tank, and not cycled at all.
 
99% of fish 'diseases' are caused by poor water quality, so that's probably what's affecting the danios too.
 
Do a 80 or 90% water change, every day, with temperature matched, dechlorinated water, until you can get the water tested; preferably with kits of your own, but if you get your LFS (local fish shop) to do it for you, it's most important that you get them to write down the actual numbers; all too often they will say "it's fine", or "a little high" and that's of no use to us at all!.

I cycled the tank for over a
Week before I introduced the danios in there everything seemed fine until I added my betta fish Thursday just gone

Fishless cycling a tank means adding ammonia on a regular basis, until the filter bacteria grow, just letting the tank run is not cycling, I'm afraid.
 
Of course everything was fine before you added the fish, because there was nothing in there to produce any toxins!
 
As I said, you'll need to do large, daily water changes until you can get test kits; you'll need to redose the whitespot medication after each water change, of course.

Okay thanks a lot just finished my first water change

Also I have a interpet internal power filter when I clean that do I turn it all off and take it all out and clean it

 

[fluttermoth]

Turn all your electrics off before you start your water change.
 
Keep a bit of the old tank water in your bucket and gently wash whatever is inside the filter in that water. You don't want to scrub it or anything, or you could wash away some of your good bacteria; just squeeze it out so all the loose dirt and bits come off. Never wash your filter media (that's all the stuff inside that the bacteria grow on) in tap water, as the chlorine will kill the bacteria.

Thanks alot ,what's the filter media sorry to be so amateur???

 

[fluttermoth]

It's all the stuff inside your filter; usually, in smaller filters, sponge, but sometimes ceramic rings or carbon.

Thanks for that your a star I thought it was gonna be smooth running looking after a tropical aquarium but its a challenge haha

Yes, it's not as easy as people think at first, but it's not that hard either.
 
Get an understanding of the nitrogen cycle and you'll be well away; remember that fishkeepers, in many senses, really don't keep fish at all; we keep water and bacteria; they keep the fish!
