Here is mine...
This about how open mine has been. I feel they need alittle adjustment time and we all need patience. Keeping mine on a plug...seems to be OK, and no attacks, but I also have these 2 clams, and no1 has bothered them and as u can c, 1 is in sand, (blue, i got from buy with david from sharkys) and the goldie on the rock ( i got from mmike). The recent addition is greenish blue...blue inside, I like it...so here r the pics....
