I am upgrading my 75 gallon because of my 14" blue gigas clam that i have had for 1.5 years to a 150 cube. I purchased a wave box for the new tank and for 5 minutes of fun i put it on my 75 gallon. I got it adjusted to the tank and got the 1" wave going and just as i reached to shut it off and put it away i noticed that the clam was *diaphraming*. I dont really know how else to explan it, and im not sure how much this will occur in the larger tank but it does have me worried. The best i can explain is that water is whooshing in and out of the clam and made the flesh that spans between the two halves of the shell go up and down with the wave action. has anyone else experienced this? what did you do? how bad is this for the clam??.. i am very worried about hurting it..
