The drama continues today with another of the 1.5" peacocks belly up in the back bottom corner of the tank - not floating. Same size as the jumper yesterday. The only signs of anything I can find on him are some damage on his mouth. Could this be from another peacock? Did something with the water cause his mouth to deteriorate like this?
I haven't seen much aggression in this tank. There is definitely a dominant peacock - getting his color already at 2.5" - and possibly another one vying for dominance, but I haven't seen them really bully anybody else or each other even.
As for water quality, I've been changing twice a week. pH is stable, tap water is consistently hard and free of chlorine. The temp rocked between 79.8 and 82.4 a few times in the first week I had the fish until I found the exact spot on my heater dial to keep it where I wanted it.
Should I be adding a dechlorinator to the water even though the test strips have always shown no chlorine?
