So as you know I picked up the HUGE 15" clam last evening, I acclimated it last night and placed it in the tank. Well, today when I got home from work I wanted to reposition a couple things and it started spewing. I was fascinated by it until the tan became so cloudy I could no longer see the clam. I logged onto the net to do a little research and then started mixing up some water just incase. I have a 180 and have done a 10% water change and I am preparing for another 10%. Any suggestions, I do not want to add any additional stress to the big fella.
