Help

Long time no see folks
I need your help guys and girls.
Got home from work and tank all cloudy only angel and wrasse swimming around all other fish have disappeared (2 clowns, foxface, yellow assesser and mandarin). Shrimp ok, as are the crabs. I added a sea hare and seachem purigen 2 weeks ago, to try to get rid of hair algae which has taken over the tank, apart from that nothing different.
All stats are fine. Any ideas as to what is happening

sea hare got into a powerhead?

get a water change mixing

point powerheads at waters surface if you can

add air stone if you got one

do some tests

and look for the fish, if dead remove them

hope its all ok trod

Nope powerheads are clear, OK I'll get powerheads pointing up and do search for fish. Got no water , will have to go to LFS and get some salted. Adding air stone

 

[ben1987]

sounds like there no oxygen to me, often why water goes cloudy. hope its ok

 

[Trod]

What would cause that?? Air stone in and powerheads facing surface now
