Posted this before and couldn’t get past “some type of encrusting sponge”. Anyone seen this before? I am preparing to shut down the tank it is in and need to make some decisions on care and handling.
I did not put this in my tank on purpose, it grew on a shady and section of dry rock. I think it’s awesome and don’t want to kill it by accident
