Orlando generously donates his 5yo scat to us. First ever for us. He kept it in medium hardness freshwater all its life. Will it continue to do ok in fw? What's the species? Need scat 101.
After the initial few days it started to not do well. Something changed in its swimming and demeanor and it's got little white balls on the ends of the spines and two on the face, reminiscent of our silver datnoid problem. I've bumped the water TDS by 2x but it will take a week just to get to a 100% water change with new harder water.
