meth blue.. is very blue!

I've never used meth blue before, but my betta has a bad case
of fungus which is suddenly worsening, so I've made him up a
little tank and put the correct dose of meth blue in it.

The water is really dark!

Is it really meant to be deep blue, rather than just a slight
staining?!

Also, I was going to leave him in it for a week and then change
*all* the water.

Are bettas ok with meth blue? I've already tried him with my
favourite cure-all, Esha 2000, and tried popping him in a net
box in a large tank which I know has good water quality and
constant temperature, just to be sure... and it's got worse.

Yes, methylene blue is very blue, which is one reason while it isn't
used nowadays as much as it used to be -- it often stains sealant,
decor, etc.

Also, I was going to leave him in it for a week and then change
*all* the water.

Instead of that, how about adding some activated carbon to the filter
and doing several smaller changes?

Yes.

It's less deep this morning but it was a bit of a shock yesterday
- it was the same dark blue colour as my fish!

It's not a filtered tank; he's in isolation in a 2g tank.
I couldn't find a heater or filter small enough to handle it,
but it's perfectly stable. Normally. In any case I used this
tank so there was no filter to kill with the meth blue :/

Yes.

Thanks very much for the comments!
