Hello! Is anyone able to identify these brown spots on the base of my torch coral? I’ve been dealing with receding flesh on all my torches and I thought it was a phosphate problem (hence the heinous amount of hair algae) but I’ve got that down to a manageable level and the flesh on torches is still receded. I get great extension from them but the flesh is definitely at an unhealthy level. I’m wondering if these little bugs (snails?) are to blame? And if so, how do I go about getting rid of them. Thanks for any responses!!
