I really love my spiny oyster. It's doing so well.
I am having a hard time finding the same amount of info on it that I found on clams though.
I know maxima and crocea prefer to be on rocks and derasa in the sand. where do spiny oysters want to be?
Mine seems happy enough -almost always open and eating.
My Vortechs are moving the sand bed a little and when I rearranged the oyster to adjust for the moved sandbed I noticed some spines/new shell growth on the oysters bottom shell.
Is it trying to grow onto something? Maybe it would like a rock?
