Hi everyone, So all my mollies are huddled together at the bottom corner of my tank. They are moving around and seem lively, not actually touching the ground, and seem healthy and happy. It’s just weird that they’re all down there. My platies are moving around, but my swordtail is down there with them. No red gills, fins are up, just practically on top of one another. They’re hungry as ever and start swimming around the tank like crazy when I approach as usual. My tank is semi planted, 46 gallons and has five mollies, one swordtail, three platies, two algae eaters, 6 kuhli loaches and one ghost a shrimp. I turned on the bubbler which I forgot to do this morning. The water level is extremely high to minimize noise, so I usually turn it on to stir the water a bit. Took parameters a few days ago because one Molly was shimmying. Aside from ph being low everything else was great! Temp is at 83 F. Any ideas?
