ok, that ice christmas present of the clown trigger, ya went sour, thing dug its way into the live rock somewhere alot and i would never see it until it came out. After about a day and a half of not seeing it at all (i wasnt around to much so i figured it was just bad timing) i decided to look around for it and i found the trigger dead with a little clear slimmy coat on it. Its eyes were eaten and a little of the stomach, im assuming by the yellow tang, because today, that died. 3 little damsels are left, they are the ones that were here from the cycle. My amonia is at .50, how should i get that to go a little lower? what else should i look out for? nitrates?nitrite? any info would help, i just wanna get the water to be ok to get something new, its so empty now!
 
For a mature tank, you had too many fish for the size of your tank, but for a new one, it was a way over stocked.
The best thing you can do now is let it complete this present cycle until you have 0 ammonia and 0 nitrites, and then proceed slowly to add what you want.
If you still want an anemone, a trigger will be bad for it, as well as corals and many inverts.
If you still want a tang, research will show that it's best to add the tang to the tank last. Also, a 45g tank is not considered large enough for a tang.
 
a 45 is really not recommended, Tangs love to swim, i had a yellow tang in my 55 gallon for about a year.. was great.. Then i upgraded to a 220 gallon mainly becouse a friend gave me a Naso tang... and sence then my Yellow tang has doubled in size and loving it..

now i have heard of tangs doing well in smaller tanks.. alone.. or with one or two smaller fish.. and mint water.. with the smaller tank he will stress out much easier
 
Do a water change to reduce the ammonia levels. You'll be seeing both nitrites and nitrates spike soon, but water changes will help, and increase the odds those damsels will survive.

If you want a tank that has lots of fish, it won't be saltwater.
 
The ammonia isn't your problem

.5 ppm might be a slight stressor, but isn't going to kill your fish. What is your pH? Ammonia toxicity increases with increasing pH. You can do water exchanges to help reduce the ammonia concentrations.
