I think I may have over feed my Duncan. But it looks like the pic I will provide. I fed each head a piece of clam I bought. They ate it before with no issues. Yesterday was the day that it retracted and today looks no where near open. Parameters are ph 8.4 cal 420 mag 1290 salt 1.028 I know that’s a little high but I did a wc and miscalculated and ended up with that salt concentration and was over a week ago with no issues. Nitrate is 25 and phosphate is 0.1 the only thing that could sting it is my chalice which is about 8 inches away. Could it just be stressed from being over fed or the itis or something worse?
