only had them a day or so now but some of the tails look a little frayed and split do you think this could jst be stress and settling in?? its not all of them but most and are hovering at top of tank, water stats still fine
What temp are they at? What is the hardness of your water? Are you running an air pump? At higher tempretures the water doesn't hold the oxygen as well! Or it could just be a little bit of fighting establishing territories maybe? (sleeping areas) I found this on a site,
Water conditions for general keeping should have a pH of 5.8-7.4 with 6.3-6.9 an
optimum for most varieties. Water hardness is just as important as pH in your tank. A kH of 1-6 and gH of 2-11 are good levels to keep your tank at. The fish may live in harder water, but for long term they need soft to medium water to thrive and stay happy.
