I bought a small(3") gold maxima & during transport & when I placed it in my tank I noticed what I believe to be it's foot,coming out the bottom of it's shell. I placed it on a rock in my 46gallon with 6x39 t5's. When I woke up the next day I saw that the foot had fallen off completely. This was probably about a week ago, it seems to be doing okay but isn't as open as my crocea which is in the same tank. It does react when fish swim over but I'm not sure if it's going to make it. It seems to be attaching where I put it, towards the bottom of the tank, probably about 18" from the light. Anyone have this happen before(the foot)? Should I move it up higher or just leave it be for now & hope it survives? Any feedback would be appreciated......
