Ok thank you.
Can you tell me how I can prevent this in the future? I followed every single step from that 30 part series on BRStv, got two clowns from the same tank at the same time, introduced them in to the water with the drip method over the course of about 30 minutes, made sure salinity in water was good, feed them that Chroma Boost food once in the morning and once at night, because I heard juveniles should eat twice per day. Every feeding they jumped right at the food. They have never been shy with food, even now while sick still goes right for the food. I made sure to always top of with fresh water as it evaporated. Water temp is always 79-80 degrees, I scrub the glass every other day, and did a roughly 30% water change on Sunday(one week after they were in the tank). I am still going through the first cycle with just the clowns in there to help the cycle. I put live sand and live rock in the tank when I set it up, and I have no other fish or invertebrates and there is zero coral in the tank yet, so its literally just the sand, rock and 2 clowns. When I first set up the tank I added a bottle of dr tims live bacteria, and when I did my water change, I added the seachem prime to the new water going in, to mix it in that before adding it to the display tank and followed the directions but other than that I havent put any other chemicals in the tank. Everything seemed fine until last night when I came home and saw the spots on the fish. I check them every single day. When I feed them, or clean the glass, or even just when I want to go look at them, I will spend at least 10 minutes a day watching them(usually more) and there have been no signs of any issue until last night. I have been feeling so proud of myself for following all these steps but apparently I missed something
