Male Betta with a bad case of white spot

It won't disappear instantly - they have a 10-14 day lifespan. Most treatments work by killing the free-swimming stage which you can't see - you have to wait for the white bits you can see to burst before they can be killed. You should have started with a big water change, then followed the instructions on the treatment - if you didn't, do that now.

Yep - take it out until you have finished treating him (read the instructions on the bottle), then put a new lot in to mop up the remaining medication - remember that most treatments continue for a week or so AFTER you can no longer see the white spots (because you still have to kill the free swimming ones that hatched from the white bits). Good luck :D

Save money and don't bother with using carbon at all :wink:

Fish vary in how they cope with whitespot. I have seen some really bad cases survive in the end while some seemingly mild ones drop dead.

Find the cause while you are treating. Whitespot is a sign of stress and 99% of the time it is poor, or incorrect, water quality. What size tank is it in, how long has it been set up, and what other tank mates are with it?

Whitespot is dormant in all fresh water - it only becomes a problem when the fish gets stressed and the parasite can actually take hold. Its a bit like how humans always come into contact with germs, but seldom get infected - if we are healthy our immune system fights it off without us noticing - same for fish. 12 Litres is pretty small - the water might be dirty (filters don't remove everything), or it might have got very hot or cold, or worse, fluctuated between extremes - that will stress a fish to the point it can get sick.

You said tank cycled for 3 weeks prior with an established filter but you've had the betta for 2 weeks?

Does that mean you took an established filter and ran it on an fishless tank for a few weeks? (When did you add the bristlenose?)

If so, then the bacteria on the filter would have died since there was no fish waste for it to live on and your tank would have started cycling when you added fish.

Or have a completely misunderstood?
