Hi everyone, longtime lurker first time poster here. Would love your opinions!
I left my boyfriend in charge of my 15 gal tank while I was gone for a week. During that time, all 3 of the fish died within a day. Clownfish pair and a royal gramma. He unfortunately did not take pictures but said everyone was fine the night before, then he woke up in the morning and the royal gramma was a skeleton (I'm guessing the work of my blood red fire shrimp), the female clown was dead and white at the surface, and the male clown was barely clinging to life down on the sandbed and had "turned white" with what looked like "a sore or a bite" on side of body. He died later that day.
4 soft corals, 2 LPS corals, 5 species of macroalgae, 1 conch, 8 snails, 4 hermit crabs, and the fire shrimp are all completely fine.
Yeah, currently dealing with BOTH dinos and cyano. I already beat dinos once by dosing phosphate and nitrate and adding pods. Now it's back with a vengeance along with cyano, which was a surprise when I returned from my trip.
Could the dino resurgence and/or cyano kill the fish so quickly? Could it have been brook or velvet even though the newest addition was the royal gramma over 3 weeks ago? Overall tank is about 7 months old.
Research here leads me to rule out lack of oxygen. There was no power outage and I have a 357 gph pump with dual random flow, both aimed towards the surface in opposite directions. I also doubt coral toxin since all the corals and inverts are fine. I run carbon with a pouch clipped into the flow from one aio chamber to the next. Using RODI for all top offs.
I only do a 20% water change about once per month in order to keep nitrate/phosphate high for the macros and to keep dinos at bay (until now). Could that be the culprit somehow?
Is a 3-way aggression battle possible? The female clown was a notorious bully, but I don't understand how the male would be last one standing only to die later too.
Parameters:
1.025 salinity
0 ammonia
30 nitrate
0.1 phosphate
8 alkalinity
480 calcium
7.8 to 8 pH
Welcoming your thoughts!
