I had put my gian feather duster down into the sand so that only about an inch was sticking out. He seemed fine, then a couple days ago, he was dug up. Basically there was a big hole in the sand where he was and he was moved around in the bottom of the tank.
I moved him to the other side of the tank and placed him in a crevice in the rocks, still on the bottom. I noticed now that he comes out after lights out and my royal gramma is more active. The gramma was snooping around where the hole in the sand was.
I'm wondering if the gramma could be harassing him. Also, I had noticed the percula nipping at the crown, but since I moved it to the other side of the tank, the clown hasn't bothered it.
I also have five cromis', regal tank, small hermit, snails and a couple cleaner shrimp fyi
