7/1 in 15g qt tank added 6 drops of methylene blue to 15g, the angels seem happy on 7/3. Left on 7/3 afternoon, return 7/4 night found majestic dead.
7/4 moved the emperor to the frag tank and he is barely breathing, sometime he'll take a lap around the tank
7/9 from the 30g frag tank, moved all corals to dt and converted it to a qt tank. added 20 gallons new water (ph and temp matched) (it was only filled to 10g).
currently in qt: yellow tang, purple tang, small blue tang, hawkfish (7/9). emperor angel in qt since 7/4 barely breathing
The only thing I remember doing differently is I sanded the rust off two tongs. Thoroughly cleaned them. I used both but the rust return on one tong. If it's rust, then corals would be affected too.
All corals are fine. Especially the sun coral which hardly open.
I'm really sorry
@Johnsonlwu. This is devastating news I wish to never deliver.
