Update, I found two dead fish yesterday morning, Clownfish and firefish

. I checked my water parameter and it was normal. The rest are settling nicely tho. Most of them started eating except yellow clown goby and lawnmower blenny. Any tips on what to feed them?
Here is the result
Ammonia : 0
Nitrate : 0
Nitrite : 0
Salinit :1.025
Ph : 8.2
temp : 80
hotelbravo, I do agreed that I am over stocking, that why I picked mostly nano fish.
kenpau, thanks for input. That is exactly what I will be doing. In order to prevent ammonia spike, I will be doing 5 - 10 gallon water change every week. I also have ammonia alarm setup in the tank so, I can monitor it everyday.
