I got 6 kuhli loaches on the 15th and acclimated them to my QT. they were panic swimming up and down the glass in the corner theybpicked as "safe". 5 days later they're still panic cruising the glass. The QT is really basic. Its usually just 2 fake plants, but I added rounded gravel and a half coconut to make them a little more secure. I also laid the plants on their side to give them more cover. Should I risk a short QT so they're less stressed? Their home tank is full of drift wood and heavily planted. Should I cover the tank partway to make it half a cave? The tank gets sunlight and overspill from the t5 on my puffer tank Any other ideas or suggestions?
