Cloudy Tank Then Dead Angel

[sangah10]

Got home from school and noticed that the tank water was REALLY cloudy. Did an instant 25% water change. It looked a little bit better, a few hours later it was back to the same cloudy water again.

The next day I woke up and found my out my pregnant angelfish died. Greattttttttt.

How many gallons or litres is the tank.
How many fish and which type.
How long has the tank been set up.

Immediate water change and increase aeration.

150L tank
tanks been set up for about 1.5months, cycled etc.

has 1 common pleco, 3 adult angels

ive fixed the cloudy water problem but my 2 veiltail angels arent eating now, food flies pass their eyes and they dont even move to eat it..

what should i do

How big is the plec?

How often do you do a gravel vac.
What are your latest water stats.
Do you still have an nitrite reading.
Do the fish look pale or darker in colour.
Can they still maintain there balance.
Do they rest on the subsrate.
