Well ive updated saga with this thing
The reason why im worried its attaching to side of the rock so its not pointing upwards
this rock is at bottom of tank
and has acan echi colony on it - which I know can be aggressive to anything within touching distance
ive got updated pictures here to show whats happened all by itself this morning..
you can see in this pic the remains of the bysal that was left behind by the clam last night
it had started to attach to this half clam shell i put underneath it but as pic shows it has left that and moved to rock with acan on it ...
The grey rock was used to prop up the clam last night vertically to help it attach more to the clam shell..
of course the thing is now - shall i just leave it there ?
I will take out the clam shell that is unused now - and the rock of course but you can notice that the angle its got is being propped up somewhat by the edge of the discarded clam shell - so when i remove those things its not going to have any support under the bottom part of its shell to the sand...
should i just remove the extra things - not touch it and see what it does ?
