I got my first nem Friday. Got him home, tried to attach him where I wanted him to go.....no dice. He them tumbled across the aquarium to the other side, and had touch down. I could tell by looking at him, that he wasn't gonna stay. There was a lot of flow and he wouldn't relax. I know it's only day #2, but I had a feeling. Now were on day 3 and he has relocated. This time, he has dropped stright down, and wedged himself in to a hole/cave that isn't easily seen unless I search for it. He is around the side of the tank. He planted himself within 3-4" of my duncan coral. I think once the lights come on, he will realize that he doesn't have enough light. SO he will pack up and move again. I could be wrong, but we'll see. Lights come on in a few hours, So it will be interesting to see how he reacts. (the light you see in the photos are from my flashlight)
I fought for months with my duncan coral trying to find him a location he was happy in. He was pissing me off. Now that I have, the nem decides to move in to the same spot. So I need to move that duncan out of there before the nem kills it. So I get to fight with that relocation all over again. dammit.
Here is a picture of the nems new location that he THINKS is home.
