So I have a 55 gallon community tank that had 8 yoyo loaches, 12 Black Ruby Barbs, 12 Harlequin Rasboras, 2 BN Plecos, and a Blovian Ram.
The day before yesterday (when I got off of work, a double shift) I found 2 of the YoYos dead, with the stomachs blown out (I believe from other fish picking at them). It was the day after a 50% water change, and I immediately did another 80% change. I have been testing the water and have found no ammonia or nitrite and my nitrate was at 20 ppm before the 80%. It was around 15 ppm today.
No other fish have been dead since then sand I have been keeping a very sharp eye on them. All of the fish have been a bit riled up, and there has been a bit of scuffling between the loaches. The two that died were smaller than the rest, although they were most around the same size when I got them (only one was significantly larger). Should I get more, or let the remaining 6 settle? I can pick 3 up at the LFS and get them into QT right away.
I have seen no signs of sickness or upset in any of the other fish (lost 1 Bolivian ram a couple weeks ago to a fallen rock).
