Did my best to try and read through as many posts as possible, and I guess I'll never find a general consensus but here goes. Have had this clam for about 4 months. It's been growing and looks healthy. I placed it directly on the sandbed from day 1, and although it moved a little bit here and there, it always remained upright. Two weeks ago it fell on its side. I was planning on doing a water change that weekend, so just let it be until then. That weekend I tried to set it upright, and it was attached to the closest rock. I understand they are rock dwelling clams, and that I should've placed it on some kind of rock/clam holder from the beginning, that's my fault. I don't want to disturb it now that it's attached, but I've also read of some people carefully slicing as close to the rock as possible to move clams. I don't want to take this risk, but have also read of some people's clams not doing so well on their sides (and others who have clams on their sides for months/years).
So I guess my question is, leave it be or try and move it. I already ordered a clam holder in case I decide to move it. Any suggestions are welcomed.
