So I lost two fish recently, not sure if they died, or what. I lost a green blotch parrot fish, who was healthy, but started hiding frequently. I have now not seen it for over a week and a half. I thought maybe my sergeant majors were harrasing it, so I was able to catch one and brought it the lfs. Now, one of my chalk bass, who used to hang out with the parrot, began to hide all of the time, and now I can't find that one either. The other chalk bass is beginning to hide as well, but is still coming out to swim every now and then. My other fish are all active and out in the open. It makes me sad as I love the green blotch parrot. Any ideas on how to see if I have a pest who may be eating them? The water quality is mainly good. Sali ity is aroun 1.024, temp is 79, phosphates are a little high around .3 ish. Tank has been up fot three years, is a 90 gallon with a 55 gallon refugium and ATS I also run carbon.
