Welcome to Reef2Reef!

Sorry to hear that. The two common reasons for this to happen would be a water quality issue (like high ammonia) or a disease issue. Did you see any symptoms prior to the fish dying? What fish died and what survived?

This post explains the backgroun information we need to try to being sorting this out for you:

I just started saltwater fish tank a few weeks fish were doing fine and then this week almost all died I have 2 left from 8 that I had
You say " almost all died". When did you start this tank and how did you cycle it and how long did you cycle it?
When you brought fish home, how did you acclimate/introduce them and for how long ?

I’m betting on high ammonia as it sounds like you set up a new tank and didn’t allow it to cycle enough to handle the fish load .

That could be it. I cycled the water for 24hrs. And I was feeding fish 3 times a day

you went way too fast. I didn't add my first fish until 3 weeks...... 8 fish in a 3 week old tank is too fast.
How many gallons is your tank?

A lot longer than 24 hrs . You mistook cycling for circulating . Please don’t buy any more fish , inverts or coral . If you can see if your lfs that you purchase them from can hold them until your tank is ready .

Sorry to hear about your losses. There are a few potential issues that I see.

First: Cycling a tank is a long process, that almost always takes several weeks and sometimes over a month. In a day, very little about the conditions of the tank can change.

Second: People usually only add a fish or two at a time, with several weeks between additions. Otherwise, the bacteria that remove toxins will be overwhelmed and the ammonia will spike.

Third: I see no mention of quarantining in your posts. It is generally suggested to keep fish in a hospital tank for a while before adding them, in order to prevent and treat diseases. Some diseases wipe out groups of fish within a few days.

Fourth: Feeding three times a day is not needed for most fish, once or twice a day is good enough. Overfeeding will worsen any ammonia in the tank.

Fifth: Ocean water often contains pollutants, or has improper parameters.

I suggest testing your water thoroughly. If the ammonia levels are low or non-existent, you can probably continue with the two remaining fish. If not, please bring the fish back to your LFS, as your tank isn't ready for fish. Next, acquire a RO/DI filter. This will allow you to filter out the impurities in tap water, so that salt can be mixed in. Then use a brand of aquarium salt such as Red Sea or Instant Ocean to make your own saltwater at home. Please don't add any more fish or crustaceans until the tank has been set up for a few more weeks. This article will provide all of the information needed to get your tank back on the right track. I hope that this helps!
