Help My Fish!

[shahrezsyed]

i have a 43 gallon tank with a pair of parrot cichlids,silver dollar fish,2 pairs of clown loaches a pair of adult spawned pair of angelfish which ,m gonna rehome soon,2 pairs of dwarf gouramis, huge biological filtration(2 inches of gravel with ug filter,4 internal filters which i always keep so that i always have a cycled filter every time i buy a new aquarium. all my fish love the current exept my angels but im gonna rehome them anyway.
my stats are
0 ammonia
0 nitrate
40 nitrite (gonna do a 50 percent water change today)
ph is 7
but due to 49 degrees celsius hot weather in pakistan whatever i do i have increased aeration so much that the water is kinda almost splashing but the water is,nt getting cooler than 35 degrees celsius.
my parrot cihlids are healthy looking but are losing colour getting abit white on the bottom,my angels are fine,3 of clownloaches fine but one is hiding behind the filter all the time and is,nt moving or eating at all and 2 of my dwarf gouramis are always near the water surface looking exhausted.
my questions are
what is this discoloration on my parrot cichlids?
what will happen to my clownloach?
what,s the matter with my dwarf gouramis?
will they survive this temperature over the summer?
are all these fish compatible?
am i overstocked?

have no answer to all of your questions but to keep your tank cooler you could get some large juice bottles and freeze tank water (just incase some leaked) and float them in the top the tank this will reduce the water temp slowly you would have to maintain otherwise the temp will be going up and down which isn't good for the fish

Hopwfully someone else will come along and answer the rest of your questions for you

You have plenty of aeration so need to run a fan in the room and close curtains or blind.
Don't use ice cubes or a bottle of freezed water, Its complete waste of time as the temp soon shoots back up.
It stressed fish altering the temp and they can break out in desease.

The white patches on the fish does it look fluffy or bleached out.
Any signs of flicking and rubbing.
Any excess mucas on gills or body of the fish.
Do any fishd dart around the tank.

k but no the white patch is,nt anything like that the scales are normal but they,re almost white instead of orange and what about my clown loach??/

[shelaghfishface]

have you got fans you can use? or can you move the tanks to a room with AC?

how have you got 40 nitrite?? you will need to do lots of water changes in there to bring them down, have you got another tank with mature media in?if so swap some,

 

[shahrezsyed]

oh sorry i mixed nitrite with nitrate i meant
nitrite 0
nitrate 40

 

[WILDER]

Do the scales look bleached out.

 

[shahrezsyed]

yeah the scales do looked bleached out.

[WILDER]

If no signs of flicking and rubbing I would treat it as columnaris.
Columnaris can look like the scales are bleaching out or a white edging to scales.

You will need to treat the tank with a bacterial med that treats columnaris.

 

[shahrezsyed]

its definitely not columnaris nothin like it every thing is normal but the scales are also normal but they have turned a bit white.

 

[WILDER]

Columnaris has many disguises.
If there no signs of flicking and rubbing, darting, erratic swimming, exess slime, I would take the bacterial route.
