no, not really. It has been running for 8 1/2 months. I did get a recent spike most likely do to some new live rock, but everything has been normal for about 1 week now. Looking good and testing good.
WELL THANKS EVERYBODY.
THe actual color is very similiar to the picture. It has the brown lines, and the white is more of a cream color. It is a very cool looking clam, and i myself thought it might be tasty.
