I've just noticed an orange spot on a tentacle of a torch that I purchased two days ago. When watching closer, I noticed that are actually two of them and they seem to be inside the tentacle and they are moving up and down. Also, that tentacle has a brown line along it.
I removed the torch from my tank, but was not able to see that orange spot anymore.
What can it be?
