We found what we think is a barnacle in 1 of the heads of our torch coral.. we have 2 of these in one head! It's preventing the tentacles from opening up that surround this thing. Do we leave it or do we try to get rid of it. If we need to get rid of it, what's the best way to do so without harming our torch? I assume if we had a good camera.. it would look like this up close.
