cloudy water with white bits :S

[norbie]

i've been having troubles lately with fungus/finrot see here ---> http/www.fishforums.net/index.php?showtopic=75172

and ive now only got 1 guppy and three corys left

the water has now gone cloudy white and has lots of white bits in almost like fluff. it was also on the glass earlier until i cleaned it.

the guppy i have left who is heavily pregnant looks like she is struggling for air all the time (not at the surface though). this may be a stage in giving birth though - i dont know.

ive done a water change today, and i'll do a gravel vac tomoro

has anyone got any advice for this?

im worried im going to lose all my fish

How much and how often do you feed?

 

[norbie]

i usually only feed the corys at night (as they have finished it all off by morning) and the guppy once in the morning. not much, but the leftovers get eaten by the corys.

i do gravel vac regularly too. almost once every 2/3 days
