need help/advise...

Hi guys,

Need help/advise....

left the house this afternoon at 4pm and everything was fine.

got home at about midnite and found my mandrian & clown on the floor

they jumped out... but why??? notice the other fishes looking half dead....

took out my test kit to test the water (to understand what is wrong)

Ammonia - 0mg/l

Nitrite - 0.3mg/l

Nitrate - 12.5mg/l

I'm using Terta test kits and that all the test kits I have

Tank size : 3ft x 1.5ft x 1.5ft

What's in the tank : 1 yellow tank, 1 flame angle, 1 mandrian, 1 fire fish, 1 dotty back, 2 clowns, 1 blue damsel, 3 cleaner shrimp, 6 snails, 1 red star (all my LS are very small, most of them are less than 1 inch), 1 small Hammerhead, 2 Ricordes, 2 mushrooms, 1 fan, 2 sponge and 20kg of LRs and sand.....

now my LS are in a bucket (freshly mix salt water) with an air pump.

what should I do with the 150l of water in my tank? should i change all the water?

or should i do 50% water change...i'm not even sure what's wrong with it...

i really hope the rest of the fish can survive

any advise would be much appreciated.....
