I had a tank of gourami, with an UnderGravel Filter and a sponge
filter on. In it I had a mix of pairs of dwarf gouramis. As my final
pair I bought some honey dwarf gouramis. when selecting the pair, I
noticed that one of the fish in the tank had, what I thought, was a
cloudy eye. I asked the fish store guy but he said no its fine, so
foolishly I bought a pair anyway. I plopped them in the tank with
the other fish (no I didn't quarantine them =( ).

It could have been old age, because there was no outward sign of
illness on him and its been about two months since I had the
problem, but I'm not sure it was just old age. I would like to
restock the tank, but I was wondering if I should empty it and scrub
everything down, with either bleach or boiling water and start again
from scratch?

The problem with bleach is getting rid of it, you need a LOT of
washes. Boiling water might crack the glass and I'm not sure what it
will do to
the silicon. Emptying out the tank, cleaning everything and spreading
the gravel out and letting it all dry might do the trick.

And NEVER go back to that LFS, any owner who will give you such bad
advice is not worth trusting ever again. As for quarantine tanks, I
only
have one tank and have never had a problem. Though I look over any
fish
in the tank very carefully before buying and ask how long they have
been there etc.

Beleive me I have learnt my lesson, and no I won't be going back to that
store again.

Thanks for your advise
