Clowns?
 

1,

Try some water changes. Could be ammonia making them dart to the surface.

How long has your tank been running?

my tank hasn't been running that long but everything in it is from the tank they were previously in. i also have two corals in there and one coral is slowly fading *yea something is wrong* but very strangely the other coral is turning green on the one section and red on the other, its very strange..so far one clown has died the other one almost died but i moved it to another tank, a holding one and I'm doin water changes

Need some info on parameters: temp, salinity, ammonia, NO2, NO3, etc...

temp: 76
Ammonia: should be around 0, 0-1, although I should test again
n02 normal
n03 unknown
Other factors:
turned the pump on, they started movin to the surface but swimming well, lookin for food it appeared, then about 20 min later they stopped movin so much

Yestorday, my hermit decided to come out of its shell and couldn't get back in when it tried the next day

Could be when I turned the pump on I burst a bubble algea, but I don't see any and there weren't any last time I checked

oh yea, salinity *i checked 10 times to be sure because it was the only thing which I could think may be causing trouble* is just around 1.023, sometimes when i measure its just below or above, so average is 1.023

I also added extra conditioner when I noticed my first clown died and I moved the still alive clown with double normal conditioner and it so far is alive, moving around a bit in its holding tank

would it be smart to take my not running carbon filter and run it for a bit to possibly clean up the water?

Well, it looks like all the inhabitants are exhibiting unusual behavior. The corals are fading, the fish are lying on their sides and darting to the surface, and the hermit crab is exiting its shell...

You really should be testing for ammonia, nitrite and nitrate at this point. Even rock and sand from an existing set-up will often undergo some sort of cycle.

Where are you getting your water? How are you mixing your new saltwater?

You don't want to know what those parameters should be but what they actuallyare. Ammonia and nitrite (NO2) need to be zero or near zero - 'normal' won't cut it. If clowns (assuming they were healthy to begin with) are dying there is something seriously wrong with your parameters.

Need to know this:
- size of original tank?
- how long was original tank running?
- what livestock, how much live rock, and what other filtration was in original tank?
- size of new tank?
- how much live rock carried over, what other filtration carried over, any new liverock or filtration?
- how long has new tank been setup and what livestock was in there before the clowns?

Lastly measure ammonia and nitrite! Nitrate would be helpful too.

Not a problem...
